My OQO has a VIA chipset. From the hwconf:
class: VIDEO
bus: PCI
detached: 0
desc: "VIA Technologies, Inc. CX700M2 UniChrome PRO II Graphics"
vendorId: 1106
deviceId: 3157
subVendorId: 1106
subDeviceId: 3157
pciType: 1
pcidom: 0
pcibus: 1
pcidev: 0
pcifn: 0
When I install Centos, I default to the vesa driver, and it operates at
the monitor's native 800x480. Of course I want more and to physically
scroll the screen to see all of the content (the OQO has slide bars on
it that do cause the current active window to scroll).
When I change the monitor settings to Generic LCD 1024x768, I get that
and 800x600 as an option. If I change the screen resolution to either
800x600 or 1024x768, and log out of X and log back in, my resolution is
unchanged at 800x480.
So I tried using the VIA driver that comes with Centos. It does not
list the CX700, but, you know, give it a try.
At first I get errors from X when logging in, finally I get changes to
occur, but I am still at 800x480. Selecting 800x600 or 1024x768 mkaes
no difference. Below is my /etc/X11/xorg.conf. Any ideas on what to try?

As root: # X -configure # mv /root/xorg.conf.new /etc/X11/xorg.conf This will give you a first draft to start from. What you usually have to edit by hand: 1) keyboard layout 2) DefaultDepth (mostly 24 if you want 16 million colors) 3) Screen resolution (if you don't want the default, Modes "XxY" will do) Check the Driver section if your driver is listed OK instead of "vesa". Once this is working, you can fine-tune bits like DRI, Composite, etcetera. Cheers, Niki Kovacs

Two solutions. > Either edit /etc/inittab,Thought I would have to do that.... So I did and it made a HUGH xorg.conf.new file. With instructions to try it out by: X -config /root/xorg.conf.new Well that brought up X but no window open and left or right mouse did nothing. So back to <cntl-alt-F1> and I see messages about VNC mode (I have vncserver configured but not running), so it ws trying to do something to accomidate vncserver if I should start it up? And there are sections in the new xorg.conf that are not in the current. Like one for the mouse, a files section and the like, so I figured i would cut and paste, but first.... I have another OQO with Centos installed that has the 'default' X setup with no playing around with the Display manager, I figured I would look at its xorg.conf to get back to basics. Guess what, NO /etc/X11/xorg.conf and everything works fine with the unit's 800x480 display. I did a 'updatedb' then a 'locate xorg.conf' and all I found was a man page file. So how do it know what to do for the display in default????

If anything like DDC (I think that's what it's acronym is - Display Data Control?) is in operation, it will piuck up the proper rates automatically. I don't have a monitor section at all in my xorg.conf. But I'm running a normal "desktop" node with conventional monitor.

After you set the monitor type and display in System->Administration->Display, do you also go to System->Preferences->Screen Resolution to set that? I had a similar problem with my 16x10 monitor until I changed both. HTH mhr
I am having serious difficulties with video control on this box.... See below. William L.

I have changed inittab to: id:3:initdefault: I am logged in as root, and run: system-config-display --reconfig I go into the Hardware tab. There I see it lists my video card; when I go into configure the video card, it shows VESA (my video card is not a listed card). For the monitor type, I select LCD Monitor 1280x1024. Back to the Settings tab, I select 1024x768. I click on OK to save all this, and system-config-display ends. I then run: init 5 It comes up in 640x480 mode (according to Preferences>Screen Resolution), and no other mode is listed. I go to Administration>Display, where it lists the current mode as 640x480, I select 1024x768 and click on OK (can barely see the OK button). I open a terminal window and run init 3 to get me out of X. I run init 5 again. The login screen is at a higher resolution than before, but once I log in as root, it is back to 640x480! The display subsection in /etc/X11/xorg.conf lists only the modes: "1024x768" "800x600" "600x480". In the standard XP that comes with the units, the default resolution is 800x480 and you can increase that and use the capacitor scroll bars to scroll the screen. help....
