| Zip43 | Hello. I am having issues on a T530. I am unable to load my integrated webcam driver properly. Interestingly, while all A/v programs fail to recognize the webcam I was able to use the novelty program Hasciicam. This is no longer true. Permissions seem to be bonked on /dev/video and deleting /dev/video to allow it to repopulate does not work. I have | 00:11 |
|---|---|---|
| Zip43 | attempted to install various webcam programs, and load kernel modules to no avail. I have confirmed the webcam is enabled in UEFI/BIOS. | 00:11 |
| Zip43 | I am getting an error from v42l-utils saying "Cannot open device /dev/video0, exiting.". I was able to establish a loopback with this program, the only device it was able to display. | 00:13 |
| Zip43 | There are presently no devices in /dev/ with the name video | 00:14 |
| Zip43 | Running `mknod /dev/video0 c 81 0` produces error in the aformentioned program, saying it doesn't know what kind of device is /dev/video | 00:15 |
| amesser | First of all, does /sys/class/video4linux contain any entries? | 00:22 |
| Zip43 | No, it is an empty directory | 00:25 |
| amesser | That means the driver is not loaded | 00:25 |
| Zip43 | Remind me the driver to load? | 00:25 |
| amesser | When the proper driver is loaded and device is found, entries should show up automatically in /sys/class/... | 00:27 |
| Zip43 | There isn't a generic webcam driver? | 00:27 |
| amesser | Afterwards, udev will take care of creating /dev/video* | 00:27 |
| amesser | Generic webcam? never heard of such a thing | 00:28 |
| Zip43 | I have an integrated webcam. How do I find the proper driver? | 00:28 |
| Zip43 | I'm not finding it in LSPCI | 00:30 |
| amesser | what does lsusb say? | 00:30 |
| amesser | there should be an entry with your webcam | 00:31 |
| Zip43 | Nope. I might have to check the BIOS again, but I checked last night and saw Webcam was enabled | 00:31 |
| amesser | hmm | 00:32 |
| Zip43 | I also ntice that `thinkpad-acpi` is no longer in repo with this newest update | 00:33 |
| Zip43 | https://linux-hardware.org/index.php?id=usb:04f2-b2ea | 00:35 |
| amesser | did you try to press [fn] + [f10] ? | 00:35 |
| Zip43 | Yes | 00:35 |
| Zip43 | But on my keyboard F10 is Skip Backwards. I have camera on F6, and F7 | 00:36 |
| Zip43 | F7 opens the XFCE display resolution menu | 00:36 |
| amesser | I think you need to activate it in bios and then you also have to press the keyboard combination with [fn] | 00:36 |
| amesser | you might need to enable the [fn] button in bios as well | 00:37 |
| Zip43 | FN works, I can turn on the keyboard light. I'll doublecheck BIOS, as I checked last night and it was enabled. | 00:37 |
| amesser | ok | 00:38 |
| amesser | when you type lsmod, does it contain uvcvideo ? | 00:38 |
| Zip43 | No, only videodev 294912 0 | 00:39 |
| Zip43 | mc 61440 2 videodev,snd_usb_audio | 00:39 |
| Zip43 | video 65536 2 thinkpad_acpi,i915 | 00:39 |
| Zip43 | I will try to load that modual | 00:39 |
| amesser | ok | 00:39 |
| amesser | btw your're right ,should be [fn] + [f6] to toggle the camera. | 00:44 |
| Zip43 | After enabling the uvcvideo module, and also recreating /dev/video, and also pressing FN+F6, I am still unable to get webcam functionality | 00:45 |
| amesser | Hmm, no more ideas from m< side, sorry. | 00:46 |
| Zip43 | And it still doesn't appear in the output of either lspci or lsusb. I will have to check bios again, but I have to use my cell phone for this upcoming call.I will return later for further troubleshooting | 00:46 |
| amesser | sorry, i have to leave, late here... | 00:46 |
| Zip43 | Thak you for the help, amesser | 00:47 |
| Zip67 | Hello. A quick reboot confirmed that webcam is enabled in BIOS. However on startup I saw errors relating to USB | 00:52 |
| Zip67 | Some output | 00:52 |
| Zip67 | [ 123.512321] usb 3-1.6: new full-speed USB device number 27 using ehci-pci | 00:52 |
| Zip67 | [ 123.928266] usb 3-1.6: device not accepting address 27, error -32 | 00:52 |
| Zip67 | [ 123.928406] usb 3-1-port6: unable to enumerate USB device | 00:52 |
| Zip67 | I do not know if this is due to a broken USB port, or if this is in-fact a problem with the webcam | 00:53 |
| Zip67 | In fact, looking at the entierty of dmesg this error repeats itself and multiple power cycles occur | 00:55 |
| rustyaxe | hmm | 01:10 |
| rustyaxe | Does that go away in dmesg if you disable it in bios? | 01:10 |
| rustyaxe | if i disable it on my dell, it disappears entirely from the usb bus after a reboot. | 01:14 |
| sfox | Hello | 01:33 |
| sfox | Is there still a problem with tianocore/edk2 payload on the thinkpad t430? | 01:33 |
| sfox | I am migrating from linux to freebsd and I don't think my coreboot+grub2 can boot the freebsd installer so I think I have to replace it | 01:34 |
| sfox | I looked at heads but that seems almost exclusively for booting linux kernels | 01:34 |
| sfox | Last time i tried to use tianocore as a payload the hardware hung on boot with a black screen and needed to be recovered with a hardware flash | 01:35 |
| sfox | Sorry wrong chat | 01:45 |
| Zip67 | rustyaxe sorry for the late reply, I'll have to check still | 03:44 |
| rustyaxe | Zip67: just a thouht, it might at least narrow it down if its some other port failed, it wont go away. | 03:47 |
| ralf | Hi | 18:45 |
