Title: Screen resolution stuck on 640x480
Post by: Marktech on July 18, 2014, 06:12:46 AM

Hi, all -

I've just started using Linux Lite, and this is my first post here: I have a little problem!  ;)

My neighbours gave me an old E-System Sorrento laptop which they frankly said wasn't much cop even when it was new, but it turns out to be perfectly adequate for occasional use -- once it has a lightweight Linux distro on it.  It has an Intel Celeron C900 single-core processor, and integrated graphics: I tried a live session of Linux Lite, and installed.

The live session defaulted to a resolution of 1024-768 at 61Hz, which was perfect; but the install uses 640x480, and I can't change it.

Running xrandr gives me 640x480 as the only option.

I attach a copy of system-info output.

I'd be very grateful for any help: I'd really like to use this distro on this system, and as it stands it's not really usable!

Hi, Marktech
I'm going trough the same problem!
For what I've researched so far, I figure it's a bug with SiS graphic cards.
To confirm if you have that kind of graphic card, you may run the command:

sudo lshw -C display

If it returns you something like:

*-display UNCLAIMED     
       description: VGA compatible controller
       product: 771/671 PCIE VGA Display Adapter
       vendor: Silicon Integrated Systems [SiS]

then, probably, the problem is that bug.

For some Ubuntu versions there are some - very complicated - ways to fix it.
I still don't know if this Linux Lite version has any fix...

If you find something, please comment!

Just had the same problem with LL3.8, then upgraded to LL 4.4 and the problem remained

The following SOLVED it: (though the GUI became kinda slow since, maybe will go back to LL 3.8 and see what happens. Don't undestand why the LIVE CD GUI worked faster ...)

Open a Terminal and create a xorg.conf file

Code: [Select]

sudo leafpad /etc/X11/xorg.conf
It will open a text editor with elevated user privileges.
Now copy and paste this in it:

Quote

    Section "Device"
      Identifier "Configured Video Device"
      Driver "vesa"
    EndSection

Save xorg.conf

Reboot PC

PS: copied this solution from another post in this forum: ([ SOLVED ] 640x480 is the only available screen resolusion? )
