Can't set native resolution on Toshiba R20 laptop

Asked by Wladston Viana on 2007-04-20

After having problems to install ubuntu (see bug #107113) and installing on the text mode, I can't set the screen resolution to it's normal size (1440x900).

I have already tried the dpkg-reconfigure, selecting 1440x900, but that mode isn't still available on the "Screen Resolution" dialog. (Should this be filled as a bug ??)

I have heard about a "915resolution" hack to the kernel, but, as a simple end-user, I wish to know if there is an easy way to correctly set my resolution.

Thanks for the attention!

boot into recovery mode, and when prompted, log into terminal as root,

then type 'sudo dpkg-reconfigure xserver-xorg'

follow the instructions, and your display should, if things go well, restore itself

Sam,

Did EXACTLY as you said. Booted on safe mode, entered the command. Selected i810 as the video driver. I have set the "kernel Framebuffer" to disable (the default, i guess). Left the modules as "default" too.

On "video modes to be used by X server", I let the default go - with was the resolution that I wanted - 1550x900. It only marked THAT option on the list. When it asked for the refresh rates, I searched the manual and the online specification, and couldn't find it. Left it to the default - the only mode option I had for my native resolution was "1440x900 @ 100Hz". I have selected that one.

Selected 24 bits color depth.

When it was over, I entered "startx". The end-result is that I was back to the SAME state as I was before. Tried rebooting, but that didn't help either.

Hello
Install 915resolution package:
type "sudo apt-get install 915resolution" in terminal

reboot and reconfigure your screen
