How to enforce a screen resolution

Hello,

my old 1440x900 Monitor died, so i switched to a 1680x1050 Eizo.
No problem to run this new one with the (interpolated) resolution of 1440x900 under Windows (preserving the aspect-ratio of 16:10).
Q4Os (Orion) however doesn't offer this lower resolution 1440 any more - although it worked at 1440 with the old monitor. In contrast, resolutions like 1024x768 (which do not make any sense at all imo) are offerd.

Is there any possibilty to get other resolutions to be offered in the screen-properties?
Are there enhancements in this regards in the more recent Versions of Q4OS?

Thanks in advance!
Flex

Re: How to enforce a screen resolution

You may need to manually configure "modeline" in xorg.conf, please read for. ex. https://ubuntuforums.org/showthread.php?t=1824362

Yes, it would be worth to try the Q4OS 3 Centaurus version https://www.q4os.org/downloads1.html

Re: How to enforce a screen resolution

Thanks Q4OS-Team,

to learn more about the modeline in xorg.conf i referred to  https://wiki.ubuntuusers.de/Archiv/XServer_Modelines/
but unfortunately my /var/log/Xorg.0.log file doesn't contain an entry Supported additional Video Mode as described there.
(No entry for a 1440 resolution is mentiond here neither, Thank's intel, no wonder it doesn't appear in linux's screen properties)

The given link https://ubuntuforums.org/showthread.php?t=1824362  referres to a file xorg.conf. But where is it?
I've got no xorg.conf in /etc/X11/ to edit!

Re: How to enforce a screen resolution

You can create a basic xorg.conf using the X executable itself. As root run:

$ Xorg -configure
This will create the file /root/xorg.conf.new, which you can then copy to /etc/X11/xorg.conf:

$ cp /root/xorg.conf.new /etc/X11/xorg.conf
and edit according to your needs.

Re: How to enforce a screen resolution

Many Thanks again.
At that moment however there occur bigger problems here on my Orion-system: The updatemanager crashes:

me@flex7:~> /opt/program_files/q4os-update-manager/bin/updatemgr.exu
Could not write to file descriptor
[kcrash] Unable to start Dr. Konqi

Before, 100s of 404 Not found and "E: Fehlschlag beim holen von http://ftp.debian.org/debian/pool/... " or
"E: Einige Indexdateien konnten nicht heruntergeladen werden. Sie wurden ignoriert oder alte an ihrer Stelle benutzt."
are shown.

i want to update from version 1.8.8-n3

Edit: There seems to be a general issue with the debian ftp-server [IP: 130.89.148.12] !? What's going on there?

Re: How to enforce a screen resolution

It seems upgrade works well here. The latest Q4OS Orion version is "1.8.10-n1". You could try to update using the procedure below:
$ sudo apt update
$ sudo apt install q4os-base
$ sudo apt dist-upgrade

Unfortunately the first cmd lead to the same errors:

I've no clue what's going on here on that system... Is it possible that the router has a problem with the debian ftp-server?

Edit: i tried the following two command anyway and thet worked! Thanks!

Re: How to enforce a screen resolution

After having investigated a bunch of other problems here (which most i could resolve finally with a  sudo apt-get update) i find me now somewhat exhausted and decide to care about that resolution issue... well: another day

Many thanks for the moment!
