[Nouveau] Could Fedora-5.9.9/X-server problem be a Nouveau-problem?

[Klaus Ebbe Grue]

Hi nouveau at lists.freedesktop.org

My X-server gives a blank screen on Fedora kernel 5.9.9.

I am in doubt whether or not I should blame Nouveau for that.

I know the nvidea drivers have problems with Fedora kernel 5.9.9.

I can file a bug against Nouveau and provide logs if you think there is a remote chance that Nouveau could be the cause.

Here are some details:

Fedora 5.8.18 / X-server works fine.

I can boot into Fedora 5.9.9 runlevel 3 (no X-server).

If I boot into Fedora 5.9.9 runlevel 5 (with X-server), the screen powers off instead of giving a login prompt, but apart from that, Fedora 5.9.9 works fine and produces log files.

If I then power off and boot into Fedora 5.8.18 and read Xorg.0.log.old I can see that the X-server under Fedora 5.9.9 did not get the screen resolutions right.

Here is what monitor-edid says under both Fedora 5.9.9 and 5.8.18:

> monitor-edid
Name: PHL BDM4350
EISA ID: PHL08fa
EDID version: 1.4
EDID extension blocks: 1
Screen size: 95.3 cm x 54.3 cm (43.18 inches, aspect ratio 16/9 = 1.76)
Gamma: 2.2
Digital signal
Max video bandwidth: 600 MHz
	HorizSync 30-160
	VertRefresh 23-80
	# Monitor preferred modeline (60.0 Hz vsync, 133.3 kHz hsync, ratio 16/9, 102 dpi) (bad ratio)
	ModeLine "3840x2160" 533.25 3840 3888 3920 4000 2160 2163 2168 2222 -hsync +vsync
...

But under Fedora 5.9.9, the X-server is unaware of the 3840x2160 resolution according to Xorg.0.log.old. It also gets the screen physical size wrong.

My first cry of help is here:

That is where I leaned that the nvidea drivers have problems with Fedora 5.9.9

Cheers,
