[Nouveau] [Bug 108047] No recognition of DVI-D monitor
https://bugs.freedesktop.org/show_bug.cgi?id=108047 --- Comment #10 from Wolfgang --- Finally I got a workaround, with a lot of pain. The problem, that Nouveau doesnt find my connected DVI-display still persists. I tried to load a custom EDID-file from /lib/firmware/edid/. This failed, it seems that the driver doesnt load EDID for "not connected" displays. Forcing enabled DVI-D-1 didnt help too, I think the display is enabled to late. But for those, who want to fix wrong EDID-Data this wight work: The kms-parameter was on older kernels: drm_kms_helper.edid_firmware=edid/your_custom_edid.bin actually with newer kernels it is drm.edid_firmware=edid/your_custom_edid.bin But the idea was not so bad: how to get correct EDID-data for my DVI-monitor: I installed nvidia-driver (which freezes after 20 min but detects the monitior out of the box). The same thing like under nouveau: only the LVDS-monitor EDID is found with get-edid, but xrandr --verbose showed me the EDID of the DVI-Monitor (why? thanks you xrandr!). I wrote the EDID in a Hex-editor and parsed it with parse-edid. So I got the definitely working modeline for 1920x1200 for my DVI-Monitor. (It looks different from cvt-generated one, and I think the kernel uses the same algorithm, when I force the resolution with kms video=DVI-D-1:1920x1200e, which produced the 960x1200 monitor resolution with the 1920x1200 desktop resolution behind). So the final workaround back on nouveau is: 1.booting with video=DVI-D-1:e and starting up with 1024x768 kernel default resolution. 1.1 Also add a grub entry without enabling the DVI port because the LVDS doesnt show the LightDM login dialog, when DVI is forced enabled but not plugged in. 2.When logging in calling a script, what creates, adds and calls the right modline (stolen from nvidia-driver) for my DVI-display. Not very nice, but works. Could you explain, why nouveu doesnt detect the DVI-monitor, but nvidia does? Is this a bug? Thanks to Ilia Mirkin, who how gave me some hints. -- You are receiving this mail because: You are the assignee for the bug.___ Nouveau mailing list Nouveau@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=108047 --- Comment #9 from Wolfgang --- Another idea is, if there is a problem with der EDID-Data on DVI-D, (but there is no error in the logs, only the line that is not connected), could I fake the EDID-Data-Block somehow, to get the native resolution on my Monitor? -- You are receiving this mail because: You are the assignee for the bug.___ Nouveau mailing list Nouveau@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=108047 --- Comment #8 from Wolfgang --- Hello again, sending a friendly ping to this report. Does anybody knows, how to switch on the DVI-D Output per default, or should nouveau detect it automatically without doing anything? Is this something special from Ubuntu or normal nouveau behavior? Why does the monitor run with 960x1200 while the picture has 1920x1200 when I force 1920x1200 (this looks really like a bug), 960 is the half of 1920. (The exactly same hardware setting works with proprietary nvidia driver, but the GPU now is to old, the fitting nvidia driver is not supported by modern kernels anymore, so ubuntu deleted it from repos, and I would love to use Nouveau insted) Thank you again. -- You are receiving this mail because: You are the assignee for the bug.___ Nouveau mailing list Nouveau@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/nouveau
