I'm having the same issue. Can't seem to find a gui app that will do this.

try to use the xvesa-flavor of slitaz
find it here: http://mirror.slitaz.org/iso/3.0/flavors/

You may have luck editing the /etc/X11/xorg.conf file, at the 'Modes' line.

Also, at the GRUB screen, hit 'E' and edit the "kernel" line, appending to the end:
SCREEN=1024x768x24
as described: http://www.slitaz.org/en/doc/handbook/livecd.html#screen

Hope one of these work!

Thanks seawolf. I'm a total Linux noob, and have been trying to figure out my resolution problem for a few days. appending the end of the kernel line did it for me.

Thanks for the help.

what 'bout xvesa?
how can I change the resolution?

Can't find any GUI....

"This output shows widescreen resolutions cannot be displayed with XVesa."
Ya but, how to set one of them?

can anyone explain this...

I formatted and reinstalled SliTaz onto my HD (that's what I get for not backing up .conf files) , and attempted this same fix to correct my resolution... This time it didn't work.

I just tried it on the xorg version of slitaz-3.0.iso , doesn't work.

I wonder why it worked for me the first time? I installed off of the same .iso disc to a fresh partition, the same way I installed it the first time.

I wasn't able to find a "Modes" line in my xorg.conf or I would try the other possible fix.

With Linux you have to add configurations, sometimes even create configuration files that don't exist in the correct locations.

Go here: http://doc.slitaz.org/en:guides:xorg-xvesa / Configuring X
Start with 3. , on my dell laptop I had to do 1.,2., and 3. before xorg would work with the vesa driver.

Thank you so much for your help. I will devour that link/guide and determine to get it running like a clock.

As a lifetime windows user (mostly xp), and a causal osx user, this whole Linux thing is a bit overwhelming. I'm very excited to get to know the inner workings of the os more intimately. It's thanks to those like you that I stand a chance at successfully learning how to command and control my Linux machine.

I'll post back with my results later.

@blasphemous,
First check what resolution are available with your card:

$ Xvesa -listmodes

Then check your ~/.xsession file contents. You can report its contents, if you're stuck.

Here is an example on how to start Xvesa (found here: http://labs.slitaz.org/news/12):

$ Xvesa -ac -shadow -screen 1024x800x24 -keybd keyboard -mouse mouse,5,/dev/input/mice &

Hope it helps.
Cheers.
