XFCE seems to use X as opposed to Fedora in general and Gnome in particular who use Wayland.<br> </div> <div><br> </div> <div>If I hand compile the EDID from the screen, I find the following resolutions: Established timings: 800x600, 800x600, 800x600, 800x600, 832x624, 1024x768, 1024x768, 1024x768, 1280x1024. Standard timings: 1920x1080, 1680x1050, 1440x900, 1280x1024, 1280x960, 1280x720. Detailed timings: 3840x2160, 2560x1440, 1280x720, 720x480, 720x576, 1920x2160. The EDID looks fine as far as I can see.<br> </div> <div><br> </div> <div>I have tried all standard and detailed timings and three established timings (boot at runlevel 3, modify <span><span>90-monitor.conf, telinit 5, repeat). All resolutions except <span>3840x2160, 2560x1440</span> and <span>1920x1080</span> work acceptably. <span><span><span>3840x2160 and 2560x1440 give a black screen and a monitor poweroff. <span><span><span>1920x1080</span></span></span> gives a noisy, psychedelic screen which remotely resembles a login screen.</span></span></span></span></span></div> <div><br> </div> <div>If I boot with no <span><span>90-monitor.conf</span> </span>at all then /var/log/Xorg.0.log seems to be in conflict with itself. First, all resolutions including <span><span><span><span><span>3840x2160</span></span></span></span></span> are recognized and agree with what I got out of reading the EDID. But then Xorg.0.log says:</div> <div><br> </div> <div> <div>[ 38.974] (II) modeset(0): Not using default mode "2560x1440" (bad mode clock/interlace/doublescan)<br> <br> </div> But <span><span><span><span><span>3840x2160</span></span></span></span></span> is the default mode. <span><span><span><span><span>3840x2160</span></span></span></span></span> is the first detailed timing record. So it seems that first <span><span><span><span><span>3840x2160</span></span></span></span></span> is recognized, then ignored, then <span>2560x1440</span> is frowned upon, then used anyways.</div> <div><br> </div> <div>I have attached /var/log/messages and /var/log/Xorg.0.log from a Fedora 36 and a Fedora 34 boot. I do not yet have a kernel log, but I hope I can get one by doing an ssh into the box after the monitor goes blank.</div> <div><br> </div> <div>By the way, when I boot Fedora 36 to runlevel 3 then the monitor switches to a resolution of <span><span><span><span><span>3840x2160 and I get a tiny command line. It is when I then do telinit 5 that the screen goes blank.</span></span></span></span></span><br> </div> <p></p> <p><br> </p> <p>In preparation of asking a question on the present list, I have run through <a href="https://nouveau.freedesktop.org/TroubleShooting.html" class="OWAAutoLink" id="LPlnk632209" previewremoved="true"> https://nouveau.freedesktop.org/TroubleShooting.html</a> in general and the section "<span>Are you clear of other kernel drivers that break Nouveau</span>" in particular. I think I have no other video drivers than Nouveau, but I have done this:</p> <p><br> </p> <p><span>sudo find /usr -type f -iname "*nvidia*" -print > stdout 2>stderr</span></p> <p><br> </p> <p>I can see some nvidia stuff in stdout. In particular, I can see a file named <span> typec_nvidia.ko.xz</span>, and TroubleShooting.html warns about a file named <span> nvidia.ko</span>. Can anyone on the list tell if there is something suspicious in the attached <span>search-nvidia-stdout</span>?</p> <p><br> </p> <p>Cheers,</p> <p>Klaus</p> <br> </div> </body> </html>
