Ubuntu 9.04 problems with Toshiba R100 including resolution and sd card reader

dressler18 · 05-28-2009, 03:12 AM

okay, so first off i am new to this forum site, but i figured if anyone can answer my questions its you guys.

I have a Toshiba R100, theyre the really thin notebook without disc drives. My first problem was not being able to install an os with no cd drive, but onces i passed that bridge i figured i was set. I managed to get Ubuntu 9.04 installed on it with a usb dvd drive, and it works perfect ie. no crashes, very stable. My Problem is screen resolution, it only allows up to 800x600 and the laptop needs 1240x768 to fill the whole screen. I tried xorg and everything i could think of to get the option of 120x768 but nothing works, and whats worse is when i disconnect the ac adapter and it switches to battery it goes to a blurry screen which i imagine is 400 x 600 but displayed twice on top of each other. it will only go back to 800x600 once restarted and is imposible to use. The driver the the machine requires to my knowlegde, is trident. the other issue is the sd card reader, it has one built in and its my favorite feature however i fear that i will never get it to work with linux.

the worse part of all this is that i almost gave up on linux for the R100 and figured it would be easier to put windows back on it and use that. Unfortunately, i cant. It doesnt boot from a cd i had to install a boot loader to get ubuntu to work and i cant even figure out how to switch to a different os to solve my problem.

PLease help!!! i dont want to end up throwing this amazing computer away

Thanks,
Pete

thanks idur!!!!

that fixed my resolution problem completely!

unfortunatly i am still having the issue that when i unplug the ac adapter, it switches to a resolution that goes off the screen and stays this way unless i open display settings and change it to something else and then say not to keep the new settings, very big pain... any ideas?

scratch that i figured it out, i turned off screen dim when on battery mode and it did the trick....

did you ever get your sd card reader to work with linux?

Hello Pete,
I added vga=792 to /boot/grub/menu.list as a kernel parameter. Therefore the resolution does not change anymore. The sd card reader does not work. I does not even report anything to the syslog, when I insert a card. But for me it is not important, as I use only micro sd cards and I have an usb adapter for these,

yeah thats awesome works great... now on to the fun stuff.. did u get compiz to work?

idur · 06-17-2009, 03:00 PM

I did not try it. I do not know what compiz is, but I do like a clean non-fancy desktop, so I think compiz is not for me.
Concerning the trident-driver: when I set the option "ShadowFB to "true" the screens stays blank. I am barely able to playback mpeg stream without mplayer saying that my system is too slow. Of course h.264 encoded videos are even worse.
I tried some of the options out of the man-page from trident, my current setting are:
Section "Device"
Identifier "Configured Video Device"
Driver "trident"
Option "CyberShadow" "on"
Option "NoAccel" "off"
Option "AccelMethod" "EXA"
EndSection
All in all I am not that successfull with the trident driver.
