View Full Version : Fedora 14 and Evergreen GPU's (HD 5850)

I upgraded to Fedora 14 with the expectation that the ATI driver would support my GPU for 2D and 3D hardware acceleration. I have an HP Envy 17" laptop with an ATI Mobility HD 5850 with 1GB of RAM.

Well, the driver loads, but no hardware acceleration.

I get the following lines in the Xorg log:

[ 1683.845] (II) RADEON(0): MC_AGP_LOCATION : 0x003f0000
[ 1683.855] (==) RADEON(0): Backing store disabled
[ 1683.855] (WW) RADEON(0): Direct rendering disabled

I don't have an xorg.conf file, and based on everything I read I was expecting acceleration support. I also installed the MESA experimental driver package to see if that would change anything, but no joy.

I also have the following in the log:

[ 1683.560] (II) Loading extension DRI2
[ 1683.560] (==) Matched ati as autoconfigured driver 0
[ 1683.560] (==) Matched vesa as autoconfigured driver 1

What I'm wondering about, is why if the autoconfigured driver is "ati" do I get the ati_drv and radeon_drv as well? Is that right?

With the other messages all labeled "RADEON", it makes me wonder if something is wrong, and I'm not getting the correct driver loaded.

Any pointers would be greatly appreciated.

you could try the drivers from the rawhide repo. Here (http://forums.fedoraforum.org/showpost.php?p=1420635&postcount=10) I described how a Fedora13 user would install it. You as F14 user should skip the points one, two and five.

Or alternatively you could try the Catalyst 10.11 driver. If you want to try the catalyst 10.11 driver you should do it before you update your kernel to 2.6.36 or before you update the xorg stuff. Without patch Catalyst 10.11 will probably not work with 2.6.36 kernel and I'm not sure if the xorg-version from the rawhide repo is supported by catalyst.

If you want to try Catalyst you should install kernel-devel and kernel-headers before.

I'll try the rawhide repo. I had the Catalyst drivers installed and working, but they stopped working with the recent bug fix release of the X server, and I had to go back to the open source drivers. Thanks for the pointers.

I manually downloaded the newer xorg-x11-drv-ati* package from a Fedora Rawhide mirror along with mesa packages, which installed just fine on F14 without any other changes, and I have 2D and 3D acceleration working! It isn't perfect, and the performance isn't as good as the proprietary drivers, but it seems good enough at the moment.

I got the catalyst drivers working stable with no crashes. Using proprietary drivers from ATI and testing repo. Details here. (http://forums.fedoraforum.org/showpost.php?p=1417661&postcount=20)
