Hi nouveau@xxxxxxxxxxxxxxxxxxxxx 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: https://ask.fedoraproject.org/t/no-login-screen-after-upgrade/10618 That is where I leaned that the nvidea drivers have problems with Fedora 5.9.9 Cheers, Klaus _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
