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?

Backup your existing configuration.
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,

Of course you will have to do this with X not running. Two solutions. Either edit /etc/inittab, like this:
# Default runlevel. The runlevels used by RHS are: # 0 - halt (Do NOT set initdefault to this) # 1 - Single user mode # 2 - Multiuser, without NFS (The same as 3, if you do not have networking) # 3 - Full multiuser mode # 4 - unused # 5 - X11 # 6 - reboot (Do NOT set initdefault to this) # id:3:initdefault:
... and then reboot.
Or, as root in a graphical terminal:
# init 3
And then login as root.

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????

Of course it helps to read the relevant documentation :o)
I just indicated this method which I've been using for all the years on Linux. I began on Slackware, where there is (almost) no configuration helper, so you have to read the docs. There's no way around it. And when I switched to other distros (like CentOS), I simply kept the habit of configuring things by hand.
IIRC, I spent much time with the FreeBSD documentation about the graphical server. It's really well done, explaining everything step by step. But then, it's not something you can learn quickly in a matter of minutes. It takes some time, but it's worth it.
Have fun,

You may not need the monitor section. 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.

Something is really not working....
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....

First thought: Can you get a video driver for Linux from the manufacturer of your card? nVidia has them, so perhaps the others do if yours is not nVidia.
Second, double check on the back of your monitor (or its manual) that your horizontal and vertical refresh frequencies in the xorg.conf are within tolerances and change them if not.
Third, are you sure your video card is VESA compatible? (That one just flashed through my head - wag.)

To get out of X, just log out or type <ctrl><alt><backspace> (this works in gnome, I'm guessing it also works in kde).
Also, you could try to reset the preference to 1026x768 before restarting X.
The display subsection in /etc/X11/xorg.conf lists only the modes: "1024x768" "800x600" "600x480".
You can edit this to be anything you like, including the 800x480 or other w/s modes. Restart X and they should take effect.

It is "VIA Technologies, Inc. CX700M2 UniChrome PRO II Graphics".
OQO does not have drivers, I guess I need to check out VIA (Yom Kippur starts in a couple hours, so this will be done on friday).
Second, double check on the back of your monitor (or its manual) that your horizontal and vertical refresh frequencies in the xorg.conf are within tolerances and change them if not.
OK. DOn't know what the internal display is, will have to ask OQO, Will have to look at my external monitor (connected via a Belkin KVM).
Third, are you sure your video card is VESA compatible? (That one just flashed through my head - wag.)
Yes. that is what other LInux distro users use. I have seen messages about using xvesa driver so you can use the key to turn the monitor 90degrees. But I can't find anything about an xvesa driver for Centos.
I then run: init 5

Should be in the manual, if you have it. Otherwise, you'd have to check with the manufacturer.

Preferences (System->Preferences->Screen Resolution), although now that I think about it, the display has to come up properly first....

condolences and good luck. VIA graphics chips are abysmal, and their support is even worse. its whats left of the old S3, bought at a garage sale prices when S3 merged with Diamond to form Rio and sell MP3 players.

I've not used the GUI setup stuff, so I have no thoughts on it. When you get done futzing around with that, does your xorg.conf have multiple resolutions in it?
I then run: init 5
It comes up in 640x480 mode (according to Preferences>Screen Resolution), and no other mode is listed.
Again, GUI me no help to you. You might want to try manually editing the xorg.conf to look similar to what I showed as a starting point. Get rid of the sync lines in the monitor section and see if it still works at a basic level, at least.
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).

OK. Now if you hit <CTL><ALT><NUM+ or NUM-> does it change resolutions?
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....
I really know only a little about this stuff. My normal procedure is to *manually* set stuff up (after running the normal kudzu/system-config* stuff) to get what I want installed.
For me, debugging is much easier when the details are not hidden. So manually setting things up, and changing them, helps provide transparency.
<snip sig stuff>
ISTR that there are some config files under $HOME that have settings that are used when X is started up (but last time I looked, it was X11R6). Maybe there is something under some of those dirs?
Sorry I can't help more.

I have 4 OQOs for my test bed. Centos on 2 so far. One is working with HIP already, the other I am working on improving how it is to use Centos with. One is still running default XP, so I have a 'baseline'. The other still in the box.
Neither Centos build has video working beyond 640x480 (or 800x480, whatever it is). Want 1024x768 working.
Fixing the video is important. When I am testing HIP, I can't be remote consoleing in (where I get the resolution of the remote I am running vncviewer on), because: I am testing with IPv6 only (and vnc is broken with IPv6) and I do not want 'spurious" connections dirtying up my tcpdumps. So the systems are connected to my KVM.

I can't help wondering why you'd want a 4x3 aspect ratio on a screen that has a (roughly) 16x10 widescreen aspect ratio, but that's your baby.
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.
