[SOLVED] DEbian jessie: AMD catalyst (fglrx) installed but slow.

kaz2100 · 04-17-2014, 11:20 PM

Hya,

System
Debian jessie 64bit. (as of 15/Apr/2014)
fglrx version. 1:14.3~beta1.0-1

Situation.
glxinfo says that direct rendering is Yes, however it is very slow.

dmesg says

Code:

 <3>[fglrx:KAS_Mutex_Release] *ERROR* Mutex released without holding it.

bugs.debian.org says (bug=741397) that

Code:

Bug#739054: fixed in fglrx-driver 1:14.3~beta1.0-1

We believe that the bug you reported is fixed in the latest version of
fglrx-driver, which is due to be installed in the Debian FTP archive.

I guess I still have this error.

This happened after dist-upgrade. Kernel modules were rebuilt.

Question
Does anybody else have same problem?

cheers

Don't have this problem. Quit using the fglrx driver some time ago as the FOSS driver works very well. In fact better than the fglrx on my hardware.

you may have installed the driver but I do not think you are using it. open a terminal and type lsmod | grep fglrx and see if the module is loaded.
if not try modprobe fglrx . if you compiled it your self did you run the aticonfig --initial for a single monitor.

did you try fglrxinfo

Quote:

$ glxinfo | grep "direct rendering"

If it says "direct rendering: yes" then you're good to go! If the $ glxinfo command is not found install the mesa-demos package.

remember you can test it also

Quote:

You can also use:

fgl_glxgears

as the fglrx alternative test to glxgears.

as for this

the nouveau driver will give you the same output.

+1 -- Same experience as described by Widget. I'm using the radeon driver that comes with the kernel and it works fine. What graphics card do you have? Also this link may be of interest.

Hya,

Thanks.

My penguin looks like this HCL.

Yes, glxinfo says direct rendering is yes.

+++++
I guess I solved this problem.

I found another problem with update-initramfs, which lead me to this thread.

I removed libc-x32 (also dev package), and rebuilt kernel modules again,

aticonfig --initial (I have not done this step until today)

My penguin is in good shape now.

I am not sure which step worked.

By the way, Debian does not recommend to turn X86_x32 on for security reason. On the other hand, package manager installs libc-x32. I guess it might be somewhat preposterous.

Hya

Self reply.

I tried kernel option, X86_x32 on, libc-x32 installed. -> things look good, so far.

Anyway, thanks for everybody.

cheers
