Hello yogesh.
So it is not "soled" right?
Please look on Ubuntu Tweak if in the Third-Party Sources , you have add there at the bottom
the Ubuntu X to your Sources,then the Ubuntu Tweak the 2 of them !
open terminal:- Code: Select all
sudo apt-get update
- Code: Select all
sudo apt-get upgrade
If in any way you want to Edit all the process as you ask for here,
then after Edit all the process DO NOT RESTART THE MACHINE!
just do the process with Ubuntu Tweak then restart your machine.
Here is the all process from the start to the end:- Code: Select all
lspci
Then: Configure AIGLX Plus The Open-Source ATI Driver- Code: Select all
sudo modprobe -r fglrx
Then we run- Code: Select all
glxinfo | grep vendor
If you see ATI mentioned in the output, then you're still using the wrong driver. If you see SGI instead, everything's fine. On my notebook, the output looked like this:
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Tungsten Graphics, Inc.
If you have ATI in the output of the previous command, remove the fglrx driver like this (you can do this also if you have SGI in the output - just to go sure):
- Code: Select all
sudo apt-get remove xorg-driver-fglrx; sudo apt-get install libgl1-mesa-glx libgl1-mesa-dri
Next we have to modify /etc/X11/xorg.conf:- Code: Select all
sudo gedit /etc/X11/xorg.conf
HERE IS THE ALL WHAT HAS TO BE EDIT:Replace- Code: Select all
Section "Device"
Identifier "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]"
Driver "ati"
BusID "PCI:1:0:0"
EndSection
with- Code: Select all
Section "Device"
Identifier "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]"
Driver "radeon"
BusID "PCI:1:0:0"
Option "XAANoOffscreenPixmaps"
Option "AGPMode" "4"
Option "AGPFastWrite" "true"
Option "DisableGLXRootClipping" "true"
Option "AddARGBGLXVisuals" "true"
Option "AllowGLXWithComposite" "true"
Option "EnablePageFlip" "true"
EndSection
(Please note the added Option lines and the changed Driver line. Of course, your Identifier will look different if you use a different graphic card than I do.)
The Monitor and Screen sections in /etc/X11/xorg.conf should be alright.
Also replace- Code: Select all
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
EndSection
with- Code: Select all
Section "ServerLayout"
Option "AIGLX" "true"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
EndSection
(Please note that I added an AIGLX Option line at the top.)
And finally add the following two sections to the end of /etc/X11/xorg.conf if they don't exist elsewhere in the file:
- Code: Select all
Section "DRI"
Mode 0666
EndSection
Section "Extensions"
Option "Composite" "Enable"
EndSection
To make the changes take effect, we must restart X. We can do this by pressing Ctrl-Alt-Backspace (if this doesn't work, reboot the system).
Afterwards, run
- Code: Select all
glxinfo | grep vendor
again. You should now see that SGI is mentioned in the output:
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Tungsten Graphics, Inc.
Then run- Code: Select all
glxinfo | grep "direct rendering"
This should show the following line:
direct rendering: Yes
hope that is what you ask for my friend.
let us know if that fix the problems for you as SOLVED the issue.
Thank you.
Amir.
