Re: Display resolution 3840x2160@24rb stopped working after Upgrade from Stretch to Buster
Thanks to everybody, for all the hints. I think the way to search in, is to create an edid file and load it at boot. I searched in this direction before, I just abandoned that way because it did not work. Now the question I have is: How to create that edid file. The tool I found creates a file in a format, that is not accepted by the kernel. https://github.com/akatrevorjay/edid-generator/issues/11#issuecomment-531120166 I am using latest Debian (Buster 10.1) and put the generated .bin file in /lib/firmware/edid/.

I can't speak for Wayland. When I plug my laptop into a TV¹, I run a function that sets up the video and sound, which starts: my-hdmi is a function my-hdmi () { [ -z "$DISPLAY" ] && printf '%s\n' "No display as not running X$DISPLAY" && return 1; local Hdmi="$(-gethdminame)"; xrandr --addmode "$Hdmi" 1600x900; xrandr --output "$Hdmi" --mode 1600x900; … where -gethdminame is a function -gethdminame () { [ -n "$DISPLAY" ] && printf '%s\n' "$(xrandr | sed -e '/^HDMI/!d;s/ .*//;')" } (Sometimes it seems to be HDMI-1, sometimes HDMI1.) For some reason, our US-bought Samsung TV is coy about revealing its video modes when compared with the same model in its UK incarnation. Cheers, David.

Re: Display resolution 3840x2160@24rb stopped working after Upgrade from Stretch to Buster
Hi I have a kind of same problem. A monitor able of displaying at 1920x1080. Intel HD Graphics 620 with driver i915/modesetting. With old Stable (kernel 4.9.0-9) it was working fine. With new Stable (kernel 4.19.0-6) it set max display 1024x768. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892939 White waiting for a solution you can boot new kernel with "nomodeset" kernel parameter, then X will use vesa driver, and it is better than nothing, but not good for heavy graphics. Alternative keep kernel 4.9.0-9. Brgds Torben

Posting the Xorg log might be helpful, you might also tail the log when plugging in the monitor and see if it gives you any clues.

RE: Display Resolution (SOLVED)
Pardon the top-post, but there doesn't seem to a really relevant place to put this. In the end I downloaded the 3.5.1 kernel source code, and used make-kpkg to create a new kernel package. That has completely resolved my display issues, other than the dual monitor. I will pursue that issue separately. Thanks to all who took time to assist.

Before he gets into that, it could be worth checking with dpkg -l | grep xserver-xorg-video that the nouveau package is installed.

Why don't you run dpkg-reconfigure xserver-xorg again, and this time instead of picking "Advanced" to specify the numbers directly, choose "Medium" and pick "A monitor that can do 1024x768 at 75 Hz". I suppose this advice has the faint possibility that it will cause your monitor to melt, but I don't think so. Sorry for any confusion, I meant to reply to the list earlier, not just Mr. Vitharana.

What we should check next is /var/log/Xorg.0.log . This will show, somewhere inside it, what frequencies it expects from your display. Can you e-mail it to me off-list?

Are you sure you restarted X after modifying /etc/X11/xorg.conf? /etc/init.d/gdm restart will do it I think. I thought that this was worth checking because your attachments show that you have two xorg.conf files, and you might not know that you have to restart X entirely, not just log out and in again. (I think--I'll have to double-check.) Your first xorg.conf has low settings that would give you the poor quality you are talking about, so I wanted to make sure you were using the second xorg.conf.

Re: Display/resolution problems
Indeed. As says 'man XF86Config-4' says, "The first valid mode in this list will be the default display mode for startup". Personally, with laptops, I give it no choice- just the native rez, since anything else looks crappy / is a waste.

Thanks for all the help so far.

THanks for NE help in advance. There are a number of ways to get your XF86Config-4 to be set to your preferred resolution (which on a laptop will typically be the actual resolution of your screen). Do you know what that is? If it's 1024x768, you'd probably want your Modes lines to be something like... Modes "1024x768" If you want to be able to backtrack, you can easily keep the old line around with a hash mark to make it into a comment, like so... #Modes "800x600" "640x480" You can see what resolution your monitor is in by typing 'xwininfo -root'. I think xwininfo is in packages xutils. -- Tony Godshall -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
