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

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.

RE: Display Resolution
The nouveau version in squeeze does not support these cards, they should work in wheezy though. I'm reluctant to suggest this, but you probably need the nvidia driver (package nvidia-glx in section non-free) to get full support for your cards. Let's hope that security is not Nelson's main concern then¹. Cheers, Sven ¹ http://lwn.net/Articles/509131/ Of course security is a concern. Otherwise I'd spend a lot of money on an insecure, propriety OS full of really cool baubles. : ) I think the output of dmesg is telling me my driver does not support the cards: nouveau :03:00.0: PCI INT A - GSI 24 (level, low) - IRQ 24 nouveau :03:00.0: setting latency timer to 64 nouveau :03:00.0: Unsupported chipset 0x0c1c00a1 nouveau :03:00.0: PCI INT A disabled nouveau: probe of :03:00.0 failed with error -22 nouveau :04:00.0: enabling device (0002 - 0003) nouveau :04:00.0: PCI INT A - GSI 30 (level, low) - IRQ 30 nouveau :04:00.0: setting latency timer to 64 nouveau :04:00.0: Unsupported chipset 0x0c1c00a1 nouveau :04:00.0: PCI INT A disabled nouveau: probe of :04:00.0 failed with error -22 However, since this is a desktop system and not a production server, Wheezy is an option that I had already wondered about. In fact, I already had downloaded it before posting. Normally I exhaust all options before asking for help, but with my schedule this and next week I opted to see if there was an easy solution that I had just overlooked.

Re: Display Resolution-Frequency (Debian vs Windows)
I suspect that your monitor doesn't actually have a horizontal sync of 30 to 54, it's just wrong on the web site. 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. Hi Tom, Selecting 1024 x 768 75 Hz choosing Medium will end up with 1024 x 768 60 Hz. Now Desktop-Preferences-Screen Resolution has only 60 Hz option in dropdown for 1024 x 768. Don't no what to do. Thanks, Sanjaya Vitharana

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.

I need Something higher than or equal to 75Hz for 1024 x 768 with clear cool screen. For 87 Hz with 1024 x 768 which I get after several tries also not satisfied me. It shows some horizontal lines when you see carefully to the screen. It's interlaced, which means that it only shows every other line per cycle. This explains the lines you see when you look carefully, and also the low quality. Also when scrolling on the browser window can see how letters draged on the screen. Also it is slightly deficult to see on the screen for long time as I feel. Yeah, that's interlace for you. No Linux Driver for SiS 315_315E in there site. My Monitor is ViewSonic E50c (Frequency H: 30~54 kHz V: 50~160Hz). I Used apt-get install xserver-xorg-video-sis and tried dpkg-reconfigure xserver-xorg Since I am new to the Debian I don't no what to do more. Can anyone help. You're doing great. 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-Frequency (Debian vs Windows)
You're doing great. Thanks Are you sure you restarted X after modifying /etc/X11/xorg.conf? No I don't restart the X. Even I didn't know that could be done after changing xorg.conf without restarting the PC. (X server must be restarted entirely after reboot) What I did is, just restarted the mechine using gdm menu it takes me to the command line after reboot. ( Because I change the defeult runlevel to 3 in inittab rename /etc/rc3.d/S21gdm to /etc/rc3.d/s21gdm) Then I logged as root and execute gdm in command prompt. Then I logged to the mechine using my user account (since it don't give me to log as a root) After reading this mail I tried to start the X using startx (instead of gdm) it directly loged me as a root. But same effect, it only shows me 60/87 Hz for 1024 x 768 and previous problems are there. /etc/init.d/gdm restart will do it I think.

Re: Display/resolution problems
According to Trevor Pankonien, I just switched over from Ubuntu since debian has no problem working with my MP3 player, but now i have a new problem. The display on my laptop is sitting inside a black box/border, makeing approx half of my screen just black. I have a Sony Vaio PCG-FRV26 notebook, which comes with the ATI mobility 345 video card. anyone run into a similar problem or anyone have any ideas that they think i might want to try? My monitor usually runs at 1024x768, with a refresh of 60Hz, at least thats what it was in Windoze. I set that during the initial install, but now on boot it only has options for 800x600 and whatever the one below that is (which makes my screen totally unreadable, with lines blasting back and forth across the screen) Ubuntu by default came up with the right settings, so i have never had this problem in the past. If i remember correctly suse didnt have a problem either..i would like to stay with debian if possible. But the monitor issue will have to be resolved. I did a slight amout of tinkering with /etc/X11/XF86Config-4, but from fear of doin too much damage without knowing what i was doing i stopped. 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'.

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.
