Intel i810 screen resolution


I have Intel 82865 G w/ i810 chip set (16MB). My X11 can run only at 640x480. What could be wrong?

Any lead would be great.

Thanks

i have the i810 chipset running 24 bit @ 1024x768 on a 17" samtron 75e. could it be a monitor limitation. not sure what distro your running, but, have you tried running the xf86config program to correct it?
good luck.

Oh yes, sorry, I have a crappy 15" NEC monitor which does:

31-70kHz
55-120Hz

When I was installing SuSE 9.0 over inetnet, during the initial installation, it auto detect and the install was running at 1024x768. But after install and reboot, it only come up at 640x480. There is no other screen size I can choose.

I have tried SaX2. I picked 16bit color and it gave me 3 resolutions 648x480, 800x600, 1024x768. Then it followed a test before saving. When I run the test, it gave me a screen in I assume 640x480. And it has a msg "screen [0] : No video mode tuning available." Then I saved it. Reboot just to make sure. Result is, still the same.

Second thing I did was select 16 bits color, then checked only 1024x768. Then run the test. Reboot, and same result. I get only 640x480.

Same thing with xf86config. During xf86config, it shows I have resoultions up to 1024, but after saving it, and start Linux, I still get only 640x480 at login screen and inside any WindowsManager.

I can post my XF86Config if it helps.

I purposely removed the FontPath and InputDevice here to save space. Note the folllowing is generated by SaX2. the Intel 82865G (i810) video card has 16MB. I will post the xf86config config in next post. It's kind different.

i'm not familiar w/suse so i'll suggest running xf86config again, be sure to manually enter your hor. and vert. rates to the actual specs of the monitor, and edit the mode lines to eliminate the "1280 x 1024" option. that's all i can think of until i get home and look at my config.
good luck.

Hi PEACEDOG,

I tried that. Didn't help.

Thanks for your replies! if you can think of anything else, I really appreciate that. What puzzles me is, when I first install SuSE, it was using 1024x768 GUI during instal, but after reboot, it's always 640x480.

Thanks!

who can tell me how to solve the strange problem?
Is i t a linux bug or i do a wrong assemble file or i do a wrong operator?
It puzzle me i can use the 1024x768 256,but cann't increase the color depth.
if i change to 1024x768 thousands color mode and restart the X window, it occur an error and the X window can't run.
after i run XF86Config, the X window can run with 640x480 mode.
it confuse me for a long time, who can tell me how to sovle the problem.
Thanks

PEACEDOG,

I tried setting color depth to 24 bits, it says Video BIOS mode not avaliable. I think you are right at the beginning that it's my monitor setting that stop me from going higher resolution with more than 256 color.

Strange thing is, SaX and xf86config both said I can do 1024x768 at 24 bits, but when I am in window Manager, it won't. And as I mentioned, during initial install I was running 1024x768 at something higher than 256 colors. Possibly 16 bits.

eqiuno,

Do you have a small low end monitor too?
