Fix for black screen on reboot?

[soder]

This is what I did.
First copied.
Then in control panel changed, no overscan, vsync and AI.

htpc@htpc-desktop:/etc/ati$ sudo cp amdpcsdb amdpcsdb.TEST
htpc@htpc-desktop:/etc/ati$ diff amdpcsdb amdpcsdb.TEST 
htpc@htpc-desktop:/etc/ati$ diff amdpcsdb amdpcsdb.TEST 
156d155
< Centermode=Son
162,164d160
< [AMDPCSROOT/SYSTEM/BUSID-1:5:0-0/OpenGL]
< VSyncControl=V3
< CatalystAI=V2
172d167
< LastViewedPage=SMore Settings

Have to figuerer out how to fix the overscan.
If I edit to much in the .default, then I get no screen on boot up.

I now also noticed, that if I change things in the CCCP, like vsync and stuff, its saved to amdpcsdb, but when I later reboot, I only get black.

I have to SSH and cp amdpcsdb.default amdpcsdb..

Something are fucked up with ATI...

You could add a little startup script that just does

grep -q fixati /proc/cmdline && rm /etc/ati/amdpcsdb

then you can use for example that fixati option. You don't need to copy that file, just delete it.

OK, I will try that, but then you have to help me a little bit more. What shall be in the scrips, where shall the script be, and how do I autostart it?

Thanks

In theory it depends a bit on the distro used, but when you know which startup script is used for X, most likely something like

/etc/init.d/{g,k.x}dm

then place it there.

Then check the gdm script.

Then check the gdm script.

What script?

/Söder

[Kano]

/etc/init.d/gdm

is a shell script! You can add my example line to add handling of a new kernel option - or leave the grep out and use always

rm /etc/ati/amdpcsdb

at the beginning but after #!/bin/sh of course.

But, what shall I add for the underscan? The 4 manual lines?

I tried that in a script yesterday, moved the script to init.d, but then it didnt start.
Maybe it was cause of not removing the amdpcsdb?

BUT, if I remove that file, where will the 4 lines for underscan be written?

well you can add that after that.
