sudo apt-get --purge remove nvidia-current
sudo apt-get --purge remove nvidia-settings
I noticed in /var/log/Xorg.0.log that GLX was failing because it was trying to load the nvidia driver still- suggesting to me that some sort of autodetect when I first installed the OS (with default BIOS) told xorg to use nvidia for GLX. Meanwhile I'm using the intel driver... so there was a failure I guess.
SO... I figured I'd forcibly remove everything nvidia (although not nvidia-common) and see what would happen. And now it works. I have drop shadows and animations and everything using the integrated intel driver.
The result is that not only do I have GLX w/drop shadows and animations, but this horrendous subliminal flicker I was experiencing that made my eyes hurt is also GONE.
This will be my solution until such a time as the nvidia driver doesn't interfere with changing the volume and brightness.
Incidentally, for anyone who may be reading in the future, no xorg.conf is needed in /etc/X11 to fix this.
Also, if you're experiencing a stuttering system, try this:
as root. Just another tip i found. hopefully this will be fixed in a newer kernel...Code:
echo 1 > /sys/module/i915/parameters/semaphores
Anyone had the chance to check out the new binaries form NVIDIA? (275.9.7)
I don't have a working online connection at home so I can't check if it fixed my main issues; beeing choppy fullscreen playback on websites as vimeo and youtube (after resume from suspend)
What I did to install successfully(?) breaks down to this:
1. hit Ctrl+Alt+F1
2. sudo tellinit 3
3. sudo dpgk -r nvidia-current
4. sudo chmod -x NVIDIA[TAB].bin
5. sudo ./NVIDIA[TAB].bin
6. Follow onscreen directions.
I messed up a few times forgetting to uninstall the old drivers and had some errors linking to old so's, but just continued hitting ok until it (the driver installation) finished and ran it again.
Please let me know if any of you gain some knowledge using this new driver.
PS! Perhaps the "owner" of this thread should remove the [SOLVED] brackets?
Yes, i'm running 64bit Natty.
I don't have my machine with me now and I'm without net in my home at the moment so I can't post my uname -a
Did you create this semaphore file or is it supposed to be there?
I'm currently using the newest NVIDIA binary (275.9.7) manually installed. Perhaps this has something to do with it?
It was there already... after my system crashed (?) last night (it was blank and really hot this morning) I'm looking into a newer kernel. Trying this one... so far it works well/fast but no wireless so I'm looking into that.
Finally got internet at home again!
No improvement using the newest driver so I reverted to the nvidia-current. Still can't find the /sys/module/i915 folder or any semaphores file anywhere on my machine.
I have the exact same kernel as you had VValdo.
uname -a: 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
Anyone else have trouble finding this file or with choppy fullscreen playback on vimeo (after suspend)??
There's a newer kernel on apt-get.. My guess is that if you use .39 the stuttering will be fixed...
