Fantastic free linux distro focussed on providing fully featured multimedia authoring on modest hardwarare. It runs as  Live CD which means you don’t need to install it if you want to just test it out - find it at www.dynebolic.org

So far I’ve run it on Tabadley and it has a few problems.

try

X -configure :1
in a terminal window.

It will generate a file /root/xorg.conf.new
Copy this file to /etc/X11/xorg.conf
Then, hit Ctrl+Alt+Backspace
your screen should clear and come back at the highest resolution it can handle
if it doesn’t come back, but drops you to a command line, type “startx” and hit Enter

Hope this helps,

The vga=794 didn’t work for my computer, but searching through the archives, I found this other method.

When in dyne:bolic

1. Open up the Home folder (the second button from the top on the right
   hand side)
2. Click the up arrow to move to the parent directory
3. Open etc
4. Open X11
5. There are two files that need to be altered: xorg.conf and xorg.conf.dist
   After opening each of these files, scroll down to the “Screen” section, and then the “Display” section.
   You will see a list of resolutions in quotes for each of three “Modes”.
   Add your own computer’s native resolution to that list (e.g. “1200×800″) for each of the three modes.
6. Save xorg.conf and xorg.conf.dist after you have altered them
7. In the partition where you have dyne:bolic installed, find the dyne folder.
8. Open that folder and open the dyne.cfg file. Because this is a
   read-only file, it will ask you permission.
9. Scroll down until you find the line:
   # X_RESOLUTION=1024x786
   add another line below without the number hash (pound sign) front of it
   X_RESOLUTION=1200x800
   (of course replace the 1200×800 with whatever your native resolution
   should be)
10. Save the file. Reboot dyne:bolic.

That’s what worked for me.
