I'm new to Ubuntu and I can't get the right resolution: The only one I can choose in "monitor settings" (I'm running Lubuntu 14.04 because the laptop is too slow for Ubuntu) is 640 x 480 (with a refresh rate of 73 Hz). On Windows XP I had 1280 x 800 (at 60 Hz) and - that's the strange part - when I was booting the test version with an USB stick I could choose between 640 x 480 and 1024 x768! Does anyone have an idea what might have happened?
The laptop is an Esprimo Mobile v5535 with a sis 672 graphic card. I've already found out that this graphic card makes some trouble and that there is no supported driver (I've already checked the "additional drivers").
What I have tried out so far:
Using xrandr (cvt --> newmode --> addmode --> output), following i.e. this link. I do create a new mode but the resolution doesn't change when I try to apply it.
Here is what
xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480 default connected 640x480+0+0 0mm x 0mm 640x480 73.0*
As it also says "maximum 640 x 480", I tried to increase the virtual screen following this (at one point - I don't remember when - I got this "screen cannot be larger than 640 x 480"-message). This only led to a black screen and I had to reactivate the backup of xorg.conf.
Since at the beginning I didn't have any xorg.conf-file, I created a new file which I simply named xorg.conf containing the following:
Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" HorizSync 30.0-62.0 VertRefresh 50.0-70.0 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1024x768" "800x600" EndSubSection EndSection
I then moved it to /etc/X11 because I read this in a website (to which I don't remember the link). Don't know whether this is how to do it (
Xorg --configure didn't work --> I only got the message that this option doesn't exist).
I really don't know how to manage the problem and I would be glad if someone could help me. And I find it very irritating that everything was ok in the test version!
EDIT: I solved the problem by installing Linux Mint 13 (!) instead of Ubuntu and it works with my graphic card. I still get only 1024 x 768 but it's ok for what I have to do.
