BIOS privacy is off and the physical has been checked. I'm not sure I'm reading this right, but it looks like the VSC chain might not be coming up. `mei_vsc_hw` is loaded but unbound. `mei_vsc`, `intel_vsc`, `ivsc_csi`, `ivsc_ace` aren't loaded at all. The ov2740 probe complains about missing rails (AVDD/DOVDD/DVDD, "supply X not found, using dummy regulator"), which I think the VSC normally provides. Tracing back, the ACPI path looks like:     \_SB_.PC00.SPI1.SPFD HID INTC1094     \_SB_.PC00.SPI1.SPFD.CVFD HID INTC1095 `INTC1094` is one of `mei_vsc_hw`'s alias matches. But the parent device for `\_SB_.PC00.SPI1` shows an empty `_HID` in /sys, so I don't think the kernel is instantiating a SPI controller on that node. If that's right, INTC1094 and INTC1095 never become spi_devices and `mei_vsc_hw` has nothing to bind to. That's my best guess at where it falls over, but I could easily be off. A couple of side notes in case they matter: * The PCH SPI controller (PCI 0000:00:1f.5, spi0) has one child for the BIOS flash. spi-nor fails JEDEC identification on it ("unrecognized JEDEC id bytes: f7 30 30 09 03 00"). I think this is unrelated. * There's an Intel USB-LJCA bridge (8086:0b63) at HS08 / INTC1098 that brings up spi1 via spi_ljca. spi1 has no children (waiting_for_supplier=0). I'm not sure if the VSC is supposed to live here on this platform. I don't know what changed between the kernel I originally installed with and 7.0.0-14. apt history puts the HWE hop to 7.0.0-14.14 on 2026-04-23 and nothing else camera-related changed in that transaction.

The IPU6 driver is happy: intel-ipu6 0000:00:05.0: Found supported sensor INT3474:01 intel-ipu6 0000:00:05.0: Connected 1 cameras But every app that tries to open the camera fails the same way: spa.v4l2: /dev/video0: VIDIOC_S_PARM: Inappropriate ioctl for device spa.v4l2: '/dev/video0' VIDIOC_STREAMON: Link has been severed Cheese, Firefox, Chromium and Zoom all behave identically. BIOS privacy is off and the FN-toggle has been checked. I'm not sure I'm reading this right, but it looks like the VSC chain might not be coming up. `mei_vsc_hw` is loaded but unbound. `mei_vsc`, `intel_vsc`, `ivsc_csi`, `ivsc_ace` aren't loaded at all. The ov2740 probe complains about missing rails (AVDD/DOVDD/DVDD, "supply X not found, using dummy regulator"), which I think the VSC normally provides. Tracing back, the ACPI path looks like: \_SB_.PC00.SPI1.SPFD HID INTC1094 \_SB_.PC00.SPI1.SPFD.CVFD HID INTC1095 `INTC1094` is one of `mei_vsc_hw`'s alias matches. But the parent device for `\_SB_.PC00.SPI1` shows an empty `_HID` in /sys, so I don't think the kernel is instantiating a SPI controller on that node. If that's right, INTC1094 and INTC1095 never become spi_devices and `mei_vsc_hw` has nothing to bind to. That's my best guess at where it falls over, but I could easily be off. A couple of side notes in case they matter: * The PCH SPI controller (PCI 0000:00:1f.5, spi0) has one child for the BIOS flash. spi-nor fails JEDEC identification on it ("unrecognized JEDEC id bytes: f7 30 30 09 03 00"). I think this is unrelated. * There's an Intel USB-LJCA bridge (8086:0b63) at HS08 / INTC1098 that brings up spi1 via spi_ljca. spi1 has no children (waiting_for_supplier=0). I'm not sure if the VSC is supposed to live here on this platform. I don't know what changed between the kernel I originally installed with and 7.0.0-14. apt history puts the HWE hop to 7.0.0-14.14 on 2026-04-23 and nothing else camera-related changed in that transaction. Happy to do whatever is helpful. Attached `diagnostics.txt` has DMI, package versions, lsmod, lspci/lsusb, the spi_master tree, the relevant ACPI nodes, and the IPU6/MEI/VSC/OV2740/LJCA kernel and libcamera/pipewire log lines. --- ProblemType: Bug ApportVersion: 2.34.0-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: atb 3887 F.... pipewire atb 3902 F.... wireplumber /dev/snd/seq: atb 3887 F.... pipewire CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 26.04 InstallationDate: Installed on 2026-05-17 (2 days ago) InstallationMedia: Ubuntu 26.04 "Resolute Raccoon" - Release amd64 (20260423.1) MachineType: LENOVO 21E8002YSG Package: linux (not installed) ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-7.0.0-15-generic root=UUID=61e8b5c4-2752-445a-93d2-a68c8bb7dd3c ro quiet splash crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M ProcVersionSignature: Ubuntu 7.0.0-15.15-generic 7.0.0 RebootRequiredPkgs: Error: path contained symlinks.

[Bug 2148088] Re: Visual artifacts on GPU usage - Framework Desktop (Strix Halo))

OK - that's actually good in my mind as it confirms a few things: 1) It's not unique to your single system (like a platform/silicon bug) 2) It's not unique to your software setup To rule out the stutter thing, I suggest starting with the fix to https://bugs.launchpad.net/bugs/2149877. If that doesn't work; please try to add this to your kernel.

Once deadlocked, charging stops and no further plug/unplug events are detected until the EC is power-cycled (30-second power button hold or emergency reset). Hardware: Lenovo ThinkPad X1 Carbon Gen 9 (20XXS1KS0F) BIOS: N32ETA1W 1.77 (02/18/2026) - fully up to date EC firmware: N32HT57W - fully up to date per fwupdmgr CPU: Intel Core i5-1145G7 (Tiger Lake) Kernel: 7.0.0-15-generic SYMPTOMS: - USB-C charging works correctly immediately after EC power cycle - After any connector change event (plug, unplug, suspend, lid close, etc), the UCSI stack sometimes freezes permanently - so far not lasted more than a few hours - /sys/class/power_supply/AC/online gets stuck on last seen value (0 or 1) - /sys/class/typec/port0-partner and port1-partner show no partner even with charger physically connected - VOLTAGE_NOW and CURRENT_NOW read 0 on both ucsi-source-psy nodes - No UCSI/typec events appear in dmesg after the freeze - silent deadlock - Only EC power cycle (30-second power button hold sometimes works - reset always works) recovers the system - modprobe -r ucsi_acpi && modprobe ucsi_acpi does NOT fix it once frozen - PCI remove/rescan of Thunderbolt devices does NOT fix it once frozen - Issue is Linux-specific; does not occur in BIOS/firmware DMESG EVIDENCE: At boot, typec ports bind correctly: typec port0: bound usb3-port5 (ops connector_ops) typec port0: bound usb2-port2 (ops connector_ops) typec port1: bound usb3-port6 (ops connector_ops) typec port1: bound usb2-port3 (ops connector_ops) After first connector event, zero further typec/ucsi messages ever appear.

[Bug 2148630] Re: Brightness control does not work at all on ROG Zephyrus G14 GA403WP laptop

Thanks for the report, and don't worry about filing against gnome- control-center — it's a natural first guess since brightness settings live in the Settings app. That said, on Ubuntu the actual backlight control is handled by the kernel (ACPI/WMI drivers like asus-wmi) which expose interfaces under /sys/class/backlight/ or /sys/class/iio/, and then by gnome-settings-daemon and mutter to make the controls work on the desktop side. The Settings panel itself just reads what those layers provide. Because this is on a daily build with kernel 7.0-rc7, it's quite possible the kernel hasn't yet created the right backlight interfaces for your OLED panel. To figure out which layer is responsible, could you run the following on the same system (or a later daily build if one is available): 1. Check whether the kernel sees any backlight devices: ls /sys/class/backlight/ 2. If that directory is empty or shows nothing relevant, check for IIO-based sensors instead: ls /sys/class/iio/device/ 3. Look for asus_wmi or ACPI video driver messages in dmesg: dmesg | grep -i "asus_wmi\|acpi_video\|oled_backlight\|backlight" 4. Check the journal for any errors when you try to change brightness (press a brightness key, wait a moment, then run): journalctl --since "10 minutes ago" | grep -i "brightness\|backlight\|asus_wmi\|g-s-d-power" If step 1 shows a device (for example asw_backlight or oled_backlight), the kernel sees it and the issue may be in gnome-settings-daemon or mutter. If the directory is empty, the kernel driver likely hasn't initialized support for your panel yet, which would be a kernel-side fix. Also, could you confirm whether the Fn+F5/F6 (or whatever) brightness keys produce any on-screen indicator at all? Even if brightness doesn't change, seeing the OSD would help narrow things down. I've noted that bug #2085359 as a related report — different model but same symptom class. If you can share the output of the commands above, I can help determine whether this should be refiled against the linux kernel package. Thanks for your patience with this and your input helps push the support forward. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are subscribed to linux in Ubuntu.

[Bug 2153080] [NEW] UCSI PPM deadlock on X1 Carbon Gen 9: any EC communication event can permanently freeze USB-C charging detection until EC power cycle

Public bug reported: On ThinkPad X1 Carbon Gen 9 (20XXS1KS0F), the UCSI PPM (Platform Policy Manager) may permanently deadlock after any EC communication event involving the USB-C/Thunderbolt charging stack. Once deadlocked, charging stops and no further plug/unplug events are detected until the EC is power-cycled (30-second power button hold or emergency reset). Hardware: Lenovo ThinkPad X1 Carbon Gen 9 (20XXS1KS0F) BIOS: N32ETA1W 1.77 (02/18/2026) - fully up to date EC firmware: N32HT57W - fully up to date per fwupdmgr CPU: Intel Core i5-1145G7 (Tiger Lake) Kernel: 7.0.0-15-generic SYMPTOMS: - USB-C charging works correctly immediately after EC power cycle - After any connector change event (plug, unplug, suspend, lid close, etc), the UCSI stack sometimes freezes permanently - so far not lasted more than a few hours - /sys/class/power_supply/AC/online gets stuck on last seen value (0 or 1) - /sys/class/typec/port0-partner and port1-partner show no partner even with charger physically connected - VOLTAGE_NOW and CURRENT_NOW read 0 on both ucsi-source-psy nodes - No UCSI/typec events appear in dmesg after the freeze - silent deadlock - Only EC power cycle (30-second power button hold sometimes works - reset always works) recovers the system - modprobe -r ucsi_acpi && modprobe ucsi_acpi does NOT fix it once frozen - PCI remove/rescan of Thunderbolt devices does NOT fix it once frozen - Issue is Linux-specific; does not occur in BIOS/firmware DMESG EVIDENCE: At boot, typec ports bind correctly: typec port0: bound usb3-port5 (ops connector_ops) typec port0: bound usb2-port2 (ops connector_ops) typec port1: bound usb3-port6 (ops connector_ops) typec port1: bound usb2-port3 (ops connector_ops) After first connector event, zero further typec/ucsi messages ever appear. No timeout, no error, no warning - the PPM simply stops responding. POWER SUPPLY STATE WHEN FROZEN: POWER_SUPPLY_STATUS=Not charging POWER_SUPPLY_VOLTAGE_NOW=0 POWER_SUPPLY_CURRENT_NOW=0 POWER_SUPPLY_USB_TYPE=[C] PD PD_PPS (on both ports) TRIGGERS: Any of the following seem able to trigger the freeze: - Unplugging the charger - Plugging in the charger - Suspend/resume - Lid close/open - System startup/shutdown sequence WORKAROUND: None available in software.

Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2153080 Title: UCSI PPM deadlock on X1 Carbon Gen 9: any EC communication event can permanently freeze USB-C charging detection until EC power cycle Status in linux package in Ubuntu: New Bug description: On ThinkPad X1 Carbon Gen 9 (20XXS1KS0F), the UCSI PPM (Platform Policy Manager) may permanently deadlock after any EC communication event involving the USB-C/Thunderbolt charging stack. Once deadlocked, charging stops and no further plug/unplug events are detected until the EC is power-cycled (30-second power button hold or emergency reset). Hardware: Lenovo ThinkPad X1 Carbon Gen 9 (20XXS1KS0F) BIOS: N32ETA1W 1.77 (02/18/2026) - fully up to date EC firmware: N32HT57W - fully up to date per fwupdmgr CPU: Intel Core i5-1145G7 (Tiger Lake) Kernel: 7.0.0-15-generic SYMPTOMS: - USB-C charging works correctly immediately after EC power cycle - After any connector change event (plug, unplug, suspend, lid close, etc), the UCSI stack sometimes freezes permanently - so far not lasted more than a few hours - /sys/class/power_supply/AC/online gets stuck on last seen value (0 or 1) - /sys/class/typec/port0-partner and port1-partner show no partner even with charger physically connected - VOLTAGE_NOW and CURRENT_NOW read 0 on both ucsi-source-psy nodes - No UCSI/typec events appear in dmesg after the freeze - silent deadlock - Only EC power cycle (30-second power button hold sometimes works - reset always works) recovers the system - modprobe -r ucsi_acpi && modprobe ucsi_acpi does NOT fix it once frozen - PCI remove/rescan of Thunderbolt devices does NOT fix it once frozen - Issue is Linux-specific; does not occur in BIOS/firmware DMESG EVIDENCE: At boot, typec ports bind correctly: typec port0: bound usb3-port5 (ops connector_ops) typec port0: bound usb2-port2 (ops connector_ops) typec port1: bound usb3-port6 (ops connector_ops) typec port1: bound usb2-port3 (ops connector_ops) After first connector event, zero further typec/ucsi messages ever appear. No timeout, no error, no warning - the PPM simply stops responding. POWER SUPPLY STATE WHEN FROZEN: POWER_SUPPLY_STATUS=Not charging POWER_SUPPLY_VOLTAGE_NOW=0 POWER_SUPPLY_CURRENT_NOW=0 POWER_SUPPLY_USB_TYPE=[C] PD PD_PPS (on both ports) TRIGGERS: Any of the following seem able to trigger the freeze: - Unplugging the charger - Plugging in the charger - Suspend/resume - Lid close/open - System startup/shutdown sequence WORKAROUND: None available in software. Only EC power cycle (power off, emergency reset) recovers charging functionality. Attached file: - ucsi_dmesg_full.txt: Full dmesg from boot through stuck state, captured while UCSI was frozen (charger physically connected, AC/online stuck at 0) Additional filtered log when stuck after unplug event: - dmesg filtered for power/charge/typec/ucsi events, captured while frozen.
