Fix for black screen on reboot?

[talz13]

for me is the blackscreen (freeze) gone on the next reboot after this command:
try cp /etc/ati/amdpcsdb.default /etc/ati/amdpcsdb

I will give that a try tomorrow!

What if we don't have a /etc/ati/amdpcsdb.default ? Can it be moved or deleted and forced to re create a default version through a command or reinstall?

[grantek]

Yep, try:
mv /etc/ati/amdpcsdb ~/amdpcsdb-backup
aticonfig --initial

[talz13]

Ok, after installing with the script and copying the amdpcsdb.default over top of amdpcsdb it appears to be booting to the desktop alright. Is there a way to check which driver I am using? I just want to have some verification that everything went alright. My CCC says:

Software
Catalyst Version			8.53
2D Driver Version			8.56.4
Catalyst Control Center Version		2.3

Does that look right for 8.12?

Yep, try:
mv /etc/ati/amdpcsdb ~/amdpcsdb-backup
aticonfig --initial

That doesnt work for creating a new file?

I have tried the newest Cat 9.1 and they dont work for me and my XBMC in Ubuntu 8.1. Everything is like in slow motion because of some low FPS.


I reinstalled the 8.552 from package manager, and I have created a new xorg.conf.

BUT, I have no amdpcsdb in my /usr/share/ati , and I know I need one to be able to adjust for my underscan for my plasma on HDMI/DVI.

So, my question are, HOW do I create a new amdpcsdb and make the driver use 'em?
Thanks

Have you run aticonfig --initial ? That might create the file if it's not there already.

Yes, I tried that. It didnt create anything but a new xorg.conf...

htpc@htpc-desktop:~$ aticonfig --initial
Found fglrx primary device section
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-3
aticonfig: Writing to '/etc/X11/xorg.conf' failed. Bad file descriptor.
htpc@htpc-desktop:~$

And more strange is, that I boot up with a flat screen monitor with VGA, and X start and I have picture.
I then plugg my TV in with HDMI/DVI, dual monitors, and picture on both. But underscan on the TV.

Then with
aticonfig --set-dispattrib=tmds2i,positionX:0
aticonfig --set-dispattrib=tmds2i,positionY:0
aticonfig --set-dispattrib=tmds2i,sizeX:1280
aticonfig --set-dispattrib=tmds2i,sizeY:720

I can get the underscan to disapear.
BUT before, I hade to use the setting
aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0

to get rid of the underscan permanently.
Now I have no amdpcsdb to fix my underscan in, and when I reboot, without the flat screen monitor via VGA, I also get no picture on my plasma.

via SSH I can see that X are not running....
What shall I do?

First I have to say, that catalyst 9.1 are the drivers Im gonna use.

And that it seems like the changed the path /usr/share/ati to /etc/ati for the file amdpcsdb

There where I am right now. Trying to get a picturer, not overscan, by editing the files amdpcsdb and amdpcsdb.default

Help please?

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

< 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.
