Monitor issue, no signal when i turn on monitor

Ask Fedora
1

after upgrading from 6.17 to 6.18 i have to put my computer to sleep and wake it to get display after i turn off and on the monitor. radeon 9060xt 16gb. reconnecting the hdmi does nothing. waking the computer from sleep fixes the issue. I dont want to use sleep on the computer.

seems to be the same issue.

Booting from 6.17 produces the expected behaviour?

Execute uname -a && udevadm monitor --kernel --property and toggle the monitor off and on… post the output it produces as pre-formatted text using </> from the button above.

Repeat this for a 6.17 kernel - we can then compare and contrast what udevadm sees under both kernels.

If you have the option of using DisplayPort, do you get the same issue as with HDMI?

Splendid - I’ll compare this with the same output when performing the same actions using a “working” kernel, and we’ll see if there’s anything obvious or if it’s a kernel regression.

a bitt less output with the 6.17 kernel :stuck_out_tongue:

Aye, but we can throw away all the stuff about batteries and sound cards, mice and keyboards. Only interested in the drm output.

9

switching back to updated kernel now if I dont need to do more in 6.17

These are missing from the 6.18 logs - no hotplug events means nothing ever tells the amdgpu driver that stuff was plugged in (or turned on in your case) and so the driver never restarts sending output over HDMI (have you tried with DisplayPort?).

This is probably an AMDGPU DC bug/regression but I’ve never used or owned an AMD card so this is something of a guess from me - I’d put a few quid on it though.

just did a test and ctrl+c before doing the f1 f2 thing. looks like you are on to somthing here =)

only have hdmi inn on the monitor, but have a jank dispayport to hdmi that my reciver can somehow use but not the monitor.

13

OK - if we can’t use DP then we can’t prove if it’s a full DC issue or just the HDMI part.

You may be able to double-check and confirm this regression by putting this in the command line but don’t hit enter…

echo detect | sudo tee /sys/class/drm/card1-HDMI-A-1/status

and turning off the monitor followed by turning it on to get your usual “nothing”… <pause, take deep breath, exhale> and then hit Enter.

If that kicks the monitor into life as it forces the card to re-detect plugged in stuff, you can be fairly confident it’s a regression and should be reported upstream to whoever the amdgpu driver developers are.

does not wake the monitor tho.

had to run the test more than once sense i did not know it needed the sudo psw. takes a minute for the card to stop sending hdmi signals.

Shame. Double check I guessed the card1-HDMI bit correctly - if you ls /sys/class/drm you should see it listed, like so:

Looks like I guessed correctly. Anyway - it’s regression and will likely get fixed pretty quickly if you report it upstream with those two logs you produced here.
