xfce4 change screen resolution

al2pet · 07-24-2012, 03:00 AM

i have 16:9 wide screen. default screen resolution is too much, i want to decrease it but except default 1900x1200 there are only 4:3 resolutions in display settings list. i tried to manually change data in ~/.config/<blabla>/diplays.xml but that didn't help.

Hi, welcome to LQ!

What is your graphics card, which driver is your distro picking, and what resolutions
does Xorg think your monitor supports?

You should be able to find most of this information by reading /var/log/Xorg.0.log
(may require to use sudo).

Cheers,
Tink

P.S.: There's a good chance your problem is *buntu related, so I'm moving this thread
to the respective forum.

Hi! My graphics card is radeon x1900gt. Not sure what driver system uses. here's my xorg.0.log
Resolutions listed in options->display are as follows
1920x1200
1680x1050
1280x1024
1440x900
1280x960
1152x864
1024x768
832x624
800x600
640x480
720x400
Frequency in list is only 60 Hz

If you're not using a CRT monitor then you might be better off leaving the resolution as it is and setting the default system fonts larger, zooming in on web pages, and other things to make text more legible. Running an LCD/TFT/whatever you want to call it at none-native resolution could look strange and the majority of the time legibility issues can be fixed with bigger fonts.
Just my opinion and if you have other reasons fro wanting a different resolution feel free to ignore it.

You know, I just have this habit of using 1280x768 resolution with my display. Any other resolution seems uncomfortable to me. I haven't noticed earlier that those 1680x1050 and 1440x900 in list are 16:10 but they seem to me uncomfortable, too. So is there a way to set 1280x768 in xubuntu? It presents in Windows XP.

If I interpret the log correctly those resolutions are what your
monitor tells the graphics card it supports. You could always try
and force a different resolution by creating a customised modeline
in your xorg.conf.
