9500M gs DRIVERS IN UBUNTU 11.04

Please don't post in all caps. It's harder to read and looks like you are shouting, so DON'T.

Which experimental driver do you mean?

If you are having issues in Natty then log a bug. Natty is NOT stable and NOT ready. If you want an OS that works then use Maverick. If you want a half working OS and are happy to suffer glitchyness and log bug bugs to help make the OS better then by all means use Natty but expect a LOT of issues

i installed ubuntu 11.04 beta just to try it...i had 3 crashes till now and logged all the bugs...first i installed it and then i went to additional drivers...after that i saw 2 drivers ..1.nvidia driver(version current)[recommended] 2.experimental 3d support for nvidia cards...if i install the first driver i get a flickering screen witch i think isn't good...and i removed it and installed the second driver experimental..it doesn't say witch version is...now i'm using ubuntu 11.04 because it's faster and on 10.10 firefox 4 doesn't work well...in maverick i get the same flickering if i install the current driver...i always installed 173 nvidia driver witch is an older version of nvidia driver...the last driver of nvidia si 256 i think...i think that now you understand what i'am saying...i wish you could further give this issue maybe it will be fixed on this new version...that's all and thank you for the prompt answer...

Try running:

sudo nvidia-xconfig

and reboot, it may help

dreamachine@dreamachine-Aspire-5920G:~$ sudo nvidia-xconfig
[sudo] password for dreamachine:
sudo: nvidia-xconfig: command not found

How did you install the driver?

from additional driver...not from terminal...the driver installed automatically...i clicked add. driver and after that i selected driver 2 experimental...i now have that driver and it's ok...i mean the screen doesn't fliker...with the new drivers it flickers and i can't use them...

can you give the output of:

lsb_release -a; uname -a; dpkg -l | grep nvidia

Thanks

i've installed back maverick...because i wasn;t very stable..here it is ..the only driver that works in ubuntu 10.10 is 173...

i have a question...is there a chance for me to install new drivers on my 9500m gs card..because in ubuntu now only these old drivers work(i mean i installed experimental 3d support and the screen doesn't flicker that's all...they don't actually work like in maverick...with the woble windows and all that)...the new verde drivers starting from 2009 and 2010...also 2011 don't work... ...somebody said i should install restricted drivers..but where can i find them?...in windows is the same..all the new verde drivers doesn;t work...i don;t know what to do...i love my laptop...and it's a 3 year old computer it's not that old...pls answer me because i really love the new natty...thx

ok run:

sudo dpkg -P nvidia-173; sudo apt-get --purge autoremove

And it will remove the old config for the package, you can now run:

sudo apt-get install nvidia-current

And install the latest driver.

sudo nvidia-xconfig

Using X configuration file: "/etc/X11/xorg.conf".

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.

Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'

why do i get this validation error?

Because Ubuntu doesn't ship with an xorg.conf by default but if one exists it will be obeyed. The file has now being created. If you reboot you may see an improvement. If you get no desktop then reboot and hold SHIFT, then select recovery mode, then select root. You can now run:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf_old; reboot

Note the X in 'X11' is capitalized, Linux is very case sensitive
