1024 to 800x600

Hi,
Today I wanted to use my Aspire One (AO110, Linpus) to connect to a projector to do a presentation. But I couldn't find how reduce resolution to 800x600.
I get easily dual display in display menu, but I didn't have other choice than 1024x600. How I do that?
Thanks
Mel
PS Also, my presentation was always interrupt by a black screen because I didn't move mouse. Is it a setting of open office or else where? I used before OO on win on a "battery" profile and I never get this problem. Re-thanks.

 

You can open a terminal and type 'xrandr -s 800x600' probably, I don't use Linpus but that should be pretty universal.

 

Hi,
Sorry for long delay, I had access to a projector only this week. It works fine, it displays 800x600. But, I was surprise by an another problem. My windows of open office presentation fits correctly on 800x600 screen. But when I start diaporama (F5 key), it cuts a part of slide on right side! No idea why.

Also, for second time, I experiment very, very slow reaction when I change slide. I tried 3 differents presentation (2 odp, 1ppt) and it's same. On first opening, its react normally and it last couple of minutes (did'nt time it). But after a longer period (30 min or up), it becomes so slow... But I don't know if it's related to memory, vga or openoffice. I tried let openoffice open for hours without data projector connected, and I never had this problem.
So if someone have ideas... I would like to use aspire for presentation because in state it's almost unusable...
Thanks
Mel

 

Hi
I use "xfce-setting-show display" to configure an external monitor.
And the relevant part of my xorg.conf is:
----------------
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "1024x600" "800x600" "640x480"
Virtual 2048 1368
EndSubSection
EndSection
------------------
The side effect may be due to the refresh rate (60 or 75hz).
Hope it helps.
