Toshiba R100 xorg weirdness from battery

[brokenkode]

This particular bug is found in Edgy, for the Toshiba R100 laptop, this uses a trident graphics card. On dapper, there was no problems with the screen resolution, however after updating to Edgy, when booting from the battery, the screen resolution goes to 4 times as much and you only get a quarter of the administration panel. log out of x and then back in and it's solved itself.

This problem isn't available if you boot from mains, as it boots in the correct resolution as from the start.

Thanks for the report. Can you please attach your /etc/X11/xorg.conf ? Also, what kind of trident graphics card do you have?

Hey Ben, thanks for getting back to me so soon. I have attached the
xorg.conf file and the following link was a conversation I had on the ubuntu
forums as I tried to solve this problem to no avail unfortunately.

According to this link the trident card that comes with this laptop is
actually
http://uk.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/jsp/productPage.do?service=UK&PRODUCT_ID=94661

manufacturer : Trident
type : XP4™ m32 LP
memory : 32 MB
memory type : DDR Video RAM
graphics accelerator : 256 bit
connected bus : 4 x AGP bus

Not sure if this is something you can help out with as well, but the other
problem I am having at the moment is with my keyboard as well, which has
something dodgy going on with any buttons that are not the standard letters,
so ctrl alt etc are all not working. I have followed this up with another
bug report as well.

Once again thanks for your help I will definitely be talking this up on my
site (brokenkode.com)

I'm attaching your xorg.conf, so someone can look at this and try to help. Though, I noticed that your monintor settings are a little funky.

Try removing the:
SubSection "Display"
  Depth 1
  Modes "1024x768"
 EndSubSection

Through the 15.

I've never seen a graphics card/monintor that can handle 1bit of data. Also, back up your xorg.conf when you are doing this... never can be too sure what will happen.

Confirming. A friend of mine can't use Ubuntu on his notebook because of this.

I have recently run into this same problem as well with a fresh install of Ubuntu 7.10 on a Toshiba R100 as well. After some reading I've found a few other people with the same problem, namely the first link below which is another launchpad bug. As it has been mentioned before, any changes to the display backlight brightness either user initiated with the hot keys or automatically as in letting the computer go idle and dimming the display or switching from AC to battery power causes the strange resolution to be displayed where only the top left quarter of the screen is expanded to full screen on the lcd.

As mentioned above, the proper resolution can be brought back by restarting X or by switching to a virtual terminal with ctrl-alt-F1 and back, ctrl-alt-F7. Some think that ACPI is to blame however when forcing Ubuntu to use the VESA driver, brightness changes work perfectly which makes me think the problem is in the Trident XP4 driver itself.

Any help on this issue would be greatly appreciated.

I believe I managed to make this screen-zooming problem go away on my Toshiba R100 by changing the boot-loader kernel display mode used. I settled on vga=791 and have been able to change the brightness without any zooming quite a lot since. The zooming problem occassionally re-occurs after suspend I think, but not enough to be a problem for me. (I turned off the auto-dimming anyway, since I prefer to have manual control over that.)

This was on Hardy BTW. Having recently upgraded to Intrepid I seem to have lost all useful Toshiba kernel support for now...

brokenkode, thank you for reporting this bug to Ubuntu. Edgy reached EOL on April 26, 2008.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Is this reproducible on a supported release? If so, could you please run the following command in a supported release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 76120

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.
