Extact resolution at startup

Re: Extact resolution at startup

Ok. Thanks for the HowTo.
I followed the instructions inside and have installed the openchrome driver.
In xorg.conf I've changed driver from "vesa" to "openchrome".
It works! I had 1024x768 @ 85 Hz (before I can't set a refresh higher than 60 Hz).

But there are other problems.
I'm writing from Windows, because, after a reboot, I can't access in Kubuntu.
When Kubuntu starts I give my password, but it freezes and show me the log in window again.
I'm sure that the driver works because on the log in I see that refersh is on 85 Hz, but there will be some mistakes in the options in xorg.conf which causes the freeze.

I've also tried to change xorg.conf to the following:

Section "Device"
  Identifier  "Configured Video Device"
  Driver    "openchrome"
# Option    "AccelMethod" "exa"  #under development, enable to test only
  Option    "ExaScratchSize" "8192"
  Option    "MaxDRIMem" "16384"
  Option    "MigrationHeuristic" "greedy"
# Option    "EnableAGPDMA" "false" #enable if you get arifacts or redraw problems
# Option    "XaaNoImageWriteRect" #enable if you gat a freeze on boot or login
EndSection

Section "Monitor"
  Identifier  "Configured Monitor"
EndSection

Section "Extensions"
  Option    "Composite" "Enable"
EndSection

Section "Screen"
  Identifier  "Default Screen"
  Monitor   "Configured Monitor"
  Device    "Configured Video Device"
  SubSection "Display"
   Viewport  0 0
   Depth   16
   Modes   "1024x768"
  EndSubSection
EndSection

But it's the same.
I've tried also to enable Option "XaaNoImageWriteRect" #enable if you gat a freeze on boot or login, but it's the same again.
How can I fix this problem?

Re: Extact resolution at startup

does CRTL-ALT-F1 still work?

If it does, log in and do

sudo service kdm restart

then do CRTL-ALT-F1 again and see if there are any error messages.

Yes, it does.

If it does, log in and do
sudo service kdm restart
then do CRTL-ALT-F1 again and see if there are any error messages.

No errors. Only "kdm start/running, process 1500".

But the image was strange. Near to mouse cursor, there were some black rectangles...
Something is going wrong with the driver or the options in xorg.

Have you any idea?

Re: Extact resolution at startup

Those black rectangles are usually called "artifacts" - do some web searching on your exact model/chipset of video card along with "xorg.conf" and you should find some Options that may help.

As far as your logging in issue, next things to check are:

CRTL-ALT-F1

Read your log file /var/log/Xorg.0.log. It is quite large so use the "more" function like this:

cat/var/log/Xorg.0.log |more

This will allow you to read the file one page at a time. You are looking for lines that begin with (WW) which are Warnings and usually not fatal and (EE) which are errors and usually are fatal.

Once you've read the file and noted warnings/errors do these commands"

sudo service kdm stop
X

and report what happens. If it still crashes - add this section to your /etc/X11/xorg.conf file

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Ok, I'll do this when I've time.

This will allow you to read the file one page at a time. You are looking for lines that begin with (WW) which are Warnings and usually not fatal and (EE) which are errors and usually are fatal.

I've found only one warning:
(WW) CHROME(0): option "migrationheuristic" is not used

Once you've read the file and noted warnings/errors do these commands"

sudo service kdm stop
X

and report what happens.

After giving X, I leave text mode and the screen remains black. I've to enter CTRL+ALT+F1 to come back in text mode.
At this time I can see the following warnings:

The XKEYBOARD keymap compiler (xkbcomp) reports
>Warning  Type "one level" has 1 level, but <RALT> has 2 symbols
>     Ignoring extra symbols

Errors from xkbcomp are not fatal to x server:
via_video.x : viasavevideo:

If it still crashes - add this section to your /etc/X11/xorg.conf file

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Done, but it's the same.

Re: Extact resolution at startup

what's in the file ~/.xsession-errors

Re: Extact resolution at startup

Sorry but I can't find the file you've asked.

However, I'm going to be crazy with this problem.
I've changed the xorg.conf with vesa configuration and it still doesn't work!

Section "Device"
  Identifier  "Configured Video Device"
  Driver    "vesa"
EndSection

Section "Monitor"
  Identifier  "Configured Monitor"
EndSection

Section "Screen"
  Identifier  "Default Screen"
  Monitor   "Configured Monitor"
  Device   "Configured Video Device"
EndSection

The difference is that with vesa it shows me resolution of 1024x768@60Hz now (1280x1024@60Hz before). But after login it still freezes and shows me log in window again.

I don't know what to do...I can't use kubuntu anymore!
