[SOLVED] Desktop slow/choppy

amishtechie · 11-13-2009, 04:11 PM

Last night I installed Slackware 64 and I have one issue I have yet to solve. The desktop is rather choppy. I read the Xorg log and saw the xserver was using the radeonhd driver so I changed it to the ati driver, Still the same. My video card is an Ati Radeon HD 3200. Thank you.

Hi,

You could try an run without a '/etc/X11/xorg.conf' file;

Quote:

excerpt from 'CHANGES_AND_HINTS.TXT';

Speaking of Xorg, the version of Xorg shipped with Slackware 13.0 will not
(in most cases) require an /etc/X11/xorg.conf file at all. Configuration of
input devices and such is handled by HAL, and the X server autoconfigures
everything else. You can still create an xorg.conf file if you wish, or you
can create a minimal xorg.conf with only the specific contents that you wish
to override (as an example, to use a binary-only video driver).
Due to removed drivers and other such changes, it's quite possible that your
old xorg.conf will not work correctly with this version of Xorg.

Try it and see what happens, look at the '/var/log/Xorg.0.log' to see what changes.

Thank you for the reply. Nothing has really changed. I generated the xorg.conf file with X -configure and only changed the driver.Everything seems to be ok in all of the log files I examined except this.

Code:

(II) LoadModule: "fbdev"
(WW) Warning, couldn't open module fbdev
(II) UnloadModule: "fbdev"
(EE) Failed to load module "fbdev" (module does not exist, 0)

That was the only error in the file except for the error for dri being disabled. There are a couple of warning messages I do not understand.

Code:

(WW) xf86OpenConsole: setpgid failed: Operation not permitted
(WW) xf86OpenConsole: setsid failed: Operation not permitted

My card is a ATI Radeon HD2400 Pro.

Go to the ATI website and download the appropriate linux driver for your card and follow the installation instructions

It will set up your Xorg.conf file.

If you want to stick with the open source drivers, you need to at least use a 2.6.30.* kernel (such as the one from /testing on the CD/DVD, iirc) to enable 2D acceleration.

Thank you adamk75. I did want to stick with the open source drivers.

After installing that kernel, you probably want to force the radeon driver to use EXA in an xorg.conf file, as I'm not sure if that's enabled by default with the version in Slackware 13. Also, if you want 3D acceleration with the open source drivers, check the thread on here for using KMS on radeon ( http://www.linuxquestions.org/questi...-works-760963/ ).
