Figures that I recently updated to the proprietary drivers. I'll try the FOSS drivers. Mainly wanted to test performance on a low end laptop.
Just to update. I added the xorg edgers PPA and install the latest xorg ati files. Black screen is gone, performance is where I'd expect it to be for this laptop, choppy at best I do have the corrupt cursor, which I know there's a fix for.
There is way to get better performance, you need to do that: Install 3.11 kernel and enable DPM: http://askubuntu.com/questions/3247...amic-power-management-feature-in-ubuntu-13-04 Install "cpufrequtils" package and set "performance" to both DPM and CPU governor: Code: cpufreq-set -g performance echo "performance" > /sys/class/drm/card0/device/power_dpm_state You might want to add it ro /etc/rc.local Disable VSync by set "SwapbuffersWait" to false in your /etc/X11/xorg.conf: Code: Section "Device" Option "SwapbuffersWait" "false" Identifier "Card1" Driver "radeon" BusID "PCI:1:0:0" EndSection I don't sure if any of these options still required (probably all are enabled by default now), but I have those env vars in my /etc/environment: Code: export R600_DEBUG=sb export R600_STREAMOUT=1 export R600_HYPERZ=1 export R600_TILING=1 export R600_SURF=1 You can try them, but as I said even "sb" probably enabled by default now. PS: There is also known problem with overhead and slow down because of UI. Before this mod working fine to fix it partially: https://forums.uberent.com/threads/rel-slowbars-54357.50349/ I don't sure about current version, but you can try. And one other thing which might improve performance: run PA with "--nofeatures" flag. Features don't work with FOSS drivers anyway, but this flag disable their rendering completely, so it's might give you some extra FPS.
Problem is coherentui was updated to use chromium 28 and that version has gpu acceleration problems. You can send the linux chome commands to coherentui to disable gpu acceleration features. This is related to bug FS#2343
I'm getting the same problem. Start PA, Black window pops up with the Steam notification in the bottom right, and just sits there, no sound or anything.
It's not Chromium/Coherent bug, it's bug of AMD drivers. You can join others and post few words about your problem here: http://devgurus.amd.com/thread/167591 Might be then AMD will look at it at least. Chances are low, but it's only we can try. UPD: Seen your post already here.
Then the best thing we could do is to guide everyone with this problem to write a reply to the support forum thread. I guess that if they see many enough suffering from this bug it might get fixed. EDIT: but isn't there nvidia card owners with the same bug?
A long as I can say some of them have temporary problems with Coherent, but I doubt it's same bug. Open source drivers always work properly with it.
Are you sure you want to use open drivers? They're not work perfectly for every game. If yep you need to remove FGLRX and then update from this PPA: https://launchpad.net/~xorg-edgers/ archive/ppa And obviously check this my post: https://forums.uberent.com/threads/black-screen-ubuntu-13-04.52558/#post-801942
You need latest Mesa from here, but it's will be installed automatically after you add PPA. But if you new to Linux probably pen source drivers isn't suitable for you.
THANK YOU, my PA now runs to the main menu DDDDDDDDDDD, gotta try if I can play also. UDP: few texture flickers, and the sun shader bug, but otherwise it's fine.
