Bullet Proof X does not start...?

[Egon Kocjan]

I have a Radeon 9200 (R250) and 1680x1050 laptop LCD. I tried to test the new failsafe mode, so I:
1. deleted /etc/X11/xorg.conf, reboot, the display is autodetected and works properly as if nothing happend (scrolling with my synaptics pad does not work, but I guess this is not supported yet?)
2. create empty xorg.conf: touch /etc/X11/xorg.conf and reboot, the screen blinks once as if X is trying to start but nothing happens, it stays at the console login prompt, I can see gdm is running in the background with one zombie child process "kill <defunct>"

If I understand the Bullet Proof X spec., a dialog in low-res vesa mode should be shown, allowing me to configure the display settings, which does not happen.

(I am running gutsy beta right now, upgraded from feisty with update-manager -d)

Hmm, can you try this on 7.10 final or Hardy alpha3?

[Egon Kocjan (egon-kocjan)]

Ok, I run the latest Hardy and empty xorg.conf now works (X starts normally as if no config is there)

However, B.P. X still doesn't start, the same problem can be reproduced, by just changing Driver "ati" to Driver "blabla", see attachment.

process list, you can see a dead kill process

What's going on is, bulletproof-X mode attempts to use Vesa for booting, and generates an xorg.conf with what it thinks are safe defaults.

Can you please attach your /etc/X11/xorg.conf.failsafe, so we can compare the settings it's using with what actually works? Perhaps the detected BusID is wrong, or it's missing an option necessary to make it work correctly.

Also, please attach the output from lspci -vvnn.

I suspect it's probably irrelevant, but can you also indicate if you have -fglrx installed, or if you only use -ati?

[Egon Kocjan (egon-kocjan)]

I run ati driver. I've attached lspci -vvnn output

[Egon Kocjan (egon-kocjan)]

I copied xorg.conf.failsafe to xorg.conf and tried to run X (with startx) manually. I attached the log that I get.

[Egon Kocjan (egon-kocjan)]

Ok, I added this to monitor def.:
        HorizSync 60-100
        VertRefresh 50-65

failsafe xorg.conf is now able to start X, see log
