Post ID Timestamp Content User
1244450 2011-11-20 17:29:00 I recently ditched archlinux in favour of Debian (testing).
Was a breeze to setup, but have just one issue - the gl screensavers have a rather blocky movement
From this, I assume that the "screen" is not configured correctly or it is using the wrong device driver, but I am unsure how to change this.

First - lspci reports my device as such:

01:05.0 VGA compatible controller: ATI Technologies Inc RS880 [Radeon HD 4250]
- this is an onboard graphics card

So I assume from what I have read, that I can use either radeon/radeonhd/ati drivers

Now: apparently xorg.conf is depreciated in favour of evdev.
How do I find what driver evdev is using? How do I configure the screen modes of evdev?

1244451 2011-11-20 21:42:00 I've never used ATI gear so don't now much about the state of the free drivers, although I have heard it has been a bit of a mess over the last few years (one reason I have avoided them).
The ATI page at the debian wiki is at wiki.debian.org although it looks a bit old.

Have you tried xrandr to adjust settings?
edit: I think grandr is a gui front-end for it.
Again, something I have not used much as it is not very useful with nvidia drivers.

You can still use xorg.conf to configure things if evdev is not co-operating.
I've got a couple of conf files in /etc/X11/xorg.conf.d/ to set some options on my nvidia card and to make my trackpad a lot more useful.

/var/log/Xorg.0.log should give a lot of info on what is going on.

This seems to be a recent answer:

The newest driver for ATI-cards is already in the repositories. Add the contrib and non-free sections to your sources list, then do this:
Code:

apt-get update
apt-get install fglrx-control
aticonfig --initial

Then reboot.
Works on my laptop every time.

1244452 2011-11-21 04:24:00 NOTE: This will not work on wheezy/testing or sid until fglrx/Catalyst supports Xserver 1.11.x, which won't be until the Catalyst 11-11 release.
Currently Catalyst is at version 11.9; so I guess I gotta sit pretty for a while

Looks like it is in sid already if you want to pull it (and dependencies) from there.

edit: or just upgrade to Sid entirely, I've always had less hassles than running testing (just install apt-listbugs and pay attention to the output when updating :) )

Breakages are fixed a lot faster without waiting for the timeout to migrate packages down to testing.

If I wanted to go cutting edge, I'd go back to Gentoo

1244455 2011-11-21 06:58:00 Well there's only 10 days difference between testing and sid (excepting dependency and arch issues).
FWIW I've always found testing very frustrating, waiting for things to get fixed.
I put stable on machines that need to work, as it does exactly what it says on the tin.

As an aside, how did you find Arch?

1244456 2011-11-21 07:11:00 Problematic ... I only used it for a few months; and got sick of it causing issues.

I wasn't aware of the time period between sid and wheezy so thank you for that info.... but I can wait :)
