Problems with installation and VESA

Post by vaisarger »

Hi!
I unfortunately was not able to install system, but last try after whom I succeded; nevertheless I deinstalled eventually cause VESA problems.

Let's be methodical.

1) First (old) machine X didn't start because VIA chipset do not support "in any way" VESA. No X, no GBI.
2) Second PC. An old one. X started. Evry time GBI wrote files on disk, system crashed and booted again, I could never read install log. I tried for a partition, and for the entire disk.
3) My laptop. Same as before, but simply GBI exited; log diplayed me that installation stopped every time gpart was setting something on a slice or on MBR. So I went in BIOS setting, changed a parameter and I tried again. Still for partition no success, on the contrary for entire disk installation was successfull.
Now, the video problem.
Since video card is an AGP Ati radeon, card is not supported. radeonkms.ko depends on drmn.ko that is not present in /boot/kernel (there is drm2.ko,instead, but, still...). I edited xorg. conf and choosed VESA.
Problem is that the only resolution that is working displays a vertical stripe in a corner (it does so in WinXP also when it uses VESA), and when I attempt to change res in "monitor" menu section, new - lower - res doesn't work (doesn't sync).

Does anyone know how to change VESA resolution in a more effective way?

(This problem is crucial for me, because that stripe makes desktop unusable.)

Thanks for xrandr tip: I didn't know. Unfortunately I'm having problems with my Internet connection line, so I can't install it now.

This is pciconf output :

Code: Select all

vendor = 'Advanced Micro Devices [AMD] nee ATI' 
device = 'Radeon RV250 [Mobility FireGL 9000]
class = display
subclass = VGA

About installation unsuccessful, this is always last GBI command (in the log file) :

Code: Select all

gpart add -s 37944M - t freebsd-ufs -i 1 /dev/ada0s4
ERROR
Two notes:
1) Fourth slice is a FAT32 partition: it is not already UFS formatted
2) The only time I succeded in installing the system was for entire disk. (But I need dual boot...)

Could be a "GPT versus BIOS" problem?
And: What could i try to fix this partitioning problem?

When I tried Debian it installed OK but as it boots it's very verbose, and there's major "complaining" about the EDID.

That my guess what the issue is - handling a monitor with a "bad" EDID.

i had basically two problems:
1) "gpart add -s 37944M - t freebsd-ufs -i 1 /dev/ada0s4
ERROR"
no installation at all

2) "Since video card is an AGP Ati radeon, card is not supported". -> radeonkms.ko depends on drmn.ko that is not present in /boot/kernel (there is drm2.ko,instead, but, still...)


At wich issue do you mean, about "bad" EDID ?
