Screen Resolution in Ubuntu 11 - Help needed

Hi

In Ubunto 9.04 I was running in 1368 x 768, but after upgrading to 11.04 I can't jam it up to more that 1024 x 768. Why and what can I do? It's a Radeon card is there any special drivers for this and if so how do I install this?

I've looked at http://www.linuxquestions.org/questi...1-04-a-878836/

That is the video card the OP is running, installing the nVidia drives wont work, and would make a bit of a mess.

Radeon is an ATI card can I with success use those drivers? I'm also a bit pussled, in ver. 9.10 I can get the resolution... So is there any way how I can change it through setup in files, how is this done?

Thanks for your help

Please show us your /var/log/Xorg.0.log file and the output of 'xrandr'.

And /etc/X11/xorg.conf

Does it make sense that the file is not there?

Yes, it makes sense that the file is not there. It would appear that the radeon driver is not reading 1368x768 as a supported resolution from your monitor. You can try to force that resolution by using the xrandr command.

Try the following:

Code:

xrandr --newmode "1368x768_60.00"  85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync

xrandr --addmode VGA-0 "1368x768_60.00"

xrandr --output VGA-0 --mode "1368x768_60.00"

Hi

Thanks for you input, though I get this feedback in the last command:

Code:

xrandr: screen cannot be larger than 1360x1360 (desired size 1368x768)

Acordingly to http://www.thinkwiki.org/wiki/Xorg_RandR_1.2 it seems to be something with changing the virtual lines.

Can somebody translate/help :D

/H

Stupid question:

I still have my old linux installation that are able to run 1368x768, can I se in some configuration files how this is done?

Sovled in a Newbie way, - instead of haveing my LCD tv on when I installed mythunbuto I instead found my LCD screen that I'm using to my laptop and did a reinstalltion. That did the trick.
