Unity 3D Slowness
In natty/oneiric ubuntu (11.04 + 11.10) some fglrx drivers and unity are extremely slow by default, it can be improved a lot :
1. via compizconfig settings manager, general set the refresh rate ( re-draw speed of compiz ) to the highest you can ( up to 200 ) and disable "auto detect refresh rate" ,
2. disable in OpenGL settings of compiz : vsync, but enable it ( "tear-free" ) in the Ati Control Panel
In the daily 12.04 build of today and fglrx from ubuntus own repo all this is no longer necessary, unity3d is finally very fast out of the box and "just works" wonderful. But for all earlier versions the above tweaks do a lot improvements.

"Jittery" Video After Installing Manual ATI Drivers From AMD Website
I am 270% (down from 300%) new to Ubuntu, Video Settings and Mathematical Percentages. So if this is covered somewhere else, please excuse this post, I was unable to find those in my searches and I wanted to help.
In two installs of Ubuntu (11.10 and 11.04), after installing the drivers from ATI, the video would get choppy as though two interlaced streams were offset. When taking screenshots, the video looked normal (making asking for support difficult). After using this guide, I enabled Tear-Free video with no effect. Through a stroke of genius (dumb luck), I changed the image options to "use grpahics processor for scaling" (Catalyist Control Center > Display Manager > Display In Use > Adjustments) . After hitting apply, the problem was resolved.
Thanks, I have seen this before, seems it comes from an uprsaetm bug where the default settings are not correct. I can't rememeber the specific trigger for this, but it only effected some people. I'll have to re apply the old patch to force main grid on a default install. I bet what has happened now so you can't select the main grid is the remeber username/password system has kicked in as well and jammed the selection. Try doing a purge of snowglobe apt-get purge snowglobe, and also remove your ~/.snowglobeomv folder then reinstall. Then select a grid to login on the first login attempt. If you want to be really sure, start snowglobe from the command line as snowglobe loginuri which will force the login to go to the main LL grid BTW this is also how you can add other grids to the drop down list in the future if you ever want to.
Hi, I had the 12.2 proprietary driver working really well. Unfortunately I fear a apt-get upgrade may have broken the driver, so I'm trying to upgrade the driver. I've followed the instructions to first remove the existing driver which seemed to work ok - cmd line suggested I autoremove a few packages in addition to the instruction, which I have done. I've downloaded the new 12.3 driver and get to the line, sudo sh ./amd-driver-installer-12-3-x86.x86_64.run --buildpkg Ubuntu/oneiric which fails. Follows is the last bit of the script before failure......

any thoughts on how to fix this? Many thanks, Russ 184.108.40.206 12:35, 31 March 2012 (CDT)
Actually scrub this - it wasn't an update that screwed my existing driver but my SSD hardrive dying - had to reinstall from scratch anyway. --220.127.116.11 18:44, 3 April 2012 (CDT)
