Found screen res solution for Linux in 3094

I know everyone has been having issues with screen resolution in 3094 with Linux distros, I know I have. I think I may have found a workaround for now..

If I step down the bit depth to 16 bit (instead of 24 bit) resolution I am able to get any resolutions I want. I use the following command line to setup everything instead of manually editting xorg.conf for resolution. You do have to edit it to change bit depth.

sudo dpkg-reconfigure -phigh xserver.conf

Stepping through this and then editting xorg.conf to choose the 16 bit resolution and now I can get any resolution in any distro I want.

Hope this helps,
Peter

 

Danke! Yep this now works on my installs, too. Appreciate the investigation.

 

Hmmm, i'm able to switch to 1280x800 but not to 1440x900 which is my MBP's native resolution. I also tried 8 bit mode but that didn't work either.

So it's a fix for macbooks or are you able to switch to higher resolutions?

 

Fedora 6

Confirmed on Fedora 6, with a MacBook Pro.

/etc/X11/xorg.conf :

Section "Screen"

Identifier "Screen0"
Device "Videocard0"
DefaultDepth 16
SubSection "Display"

Viewport 0 0
Modes "1680x1050"
​

EndSubSection​

EndSection

In ubuntu i'm still unable to switch to anything higher than 1280x800.

 

Bart,
Did you use dpkg to reconfigure the screen res? Make sure that the 1440x900 is the first entry in your mode line as well.
I'm able to get 1440x900 on my MBP (switching to full screen and configuring that res in my corg.conf)
Strange! It is working for me on my CD MBP, don't know about the C2D model.

Cheers,
Peter

 

Btw I'm using MacBook Pro Core 2 Duo, with the settings above. Works.

1440x900 works now, i'm unable to switch to any other resolution while running X11 but i guess that's just broken in this beta. Thanks for help.

 

Bart, were you able to switch before with Ctrl Alt +/- or xvidtune? I can set any resolution I like with 24bit color, but cannot switch on the fly.
