qcam command output
This seems to be the same problem as bug 2413656, see bug 2413656 comment 1 for a workaround. Looking at your logs you can skip step 6. of the workaround. Created attachment 2118342 [details]

journalctl -b 0 -k > kernel.1211.txt
Actions checked/done following bug 2413656 comment 1 1~4: checked & okay 5. done 6. skipped 7. qcam works with low resolution. qcam return 4 errors of "Unable to get rectangle" and several warning msgs. (see attached log: qcam-output.1211.txt). Tried camera test with Teams site(https://teams.microsoft.com/v2/) in Chrome browser (chrome://flags/ PipeWire Camera support = enabled) > camera seems to be detected but only black screen comes out (see attached log: journalctl -b 0 -k > kernel.1211.txt) Created attachment 2140482 [details]
Analysis of issue from Claude Code / Opus 4.7
I encountered this same issue with my new laptop for work and and was told by internal support to open a report, but first searched and found this. Will try workaround, but wanted to assist if possible by submitting analysis from Claude, in case it helps.
Ah, I will not be performing the workaround, as this is a system maintained by my employer and kernel/driver hacking won't mesh w/that. Will wait for a patch through standard update channel. Thanks. I opened a new bug report for the same issue to avoid cluttering the existing one. My hardware may be slightly different, and the workaround isn’t working https://bugzilla.redhat.com/show_bug.cgi?id=2477461 |
