View Full Version : [ubuntu] xserver no backfill for Lucid?

Hello All,

Have to say I am loving the new Ubuntu (Lucid), however I have the same problem I do every time I upgrade and that is the maximize/minimize delay in Firefox or any open window for that matter. In the past I have installed a deb file called xserver-nobackfill and it fixes the problem, but I cannot find one for Lucid. I try an older version and it tells me a newer version is already installed. I know Lucid just came out yesterday, but I wondered if someone knew where to look, or something to try.

Many thanks in advance,

AceMan

I am having the same problem, and the previous fixes worked for me as well.

Dell Studio 1537 ATI Mobility Radeon 3450

I found a thread that had a fix for the minimize/maximize problem.

You just need to enable Direct2D

sudo aticonfig --set-pcs-str=DDX,Direct2DAccel,TRUE

Thanks to all for the responses. The new ppa for the no backfill worked for me after a reboot.


Thanks again,

When I try

sudo aticonfig --set-pcs-str=DDX,Direct2DAccel,TRUE on Lucid, I get the following error message:


No layout section was found in the file: '/etc/X11/xorg.conf'.
Please run 'aticonfig --initial' first or modify your configurationfile manually and run aticonfig again.
aticonfig: parsing the command-line failed.


Running sudo aticonfig --initall gives me this:


Found fglrx primary device section
Unable to find any supported Screen sections


What can I do?

Back up your old xorg.conf and create a new one.

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo aticonfig --initial -f
Log out and back in to restart with new xorg.conf

Ever since I did this change, some Wine-based applications (such as Microsoft Word) are looking weird. Can you please tell me how to undo this modification?

The backfill/backclear patches shouldn't be needed with recent Catalyst versions. Maybe the Catalyst version in the Lucid repos is too old. I would install the latest Cat 11.3 from AMD which is what I use on MM. (Actually Cat 11.4 should be out fairly soon)

POST UPDATED:

Excellent point. I downloaded ATI Catalyst 11.3 from AMD (http://support.amd.com/us/gpudownload/Pages/index.aspx) and then followed the instructions on this HowTo (https://help.ubuntu.com/community/BinaryDriverHowto/ATI), and now I don't have any of the problems I previously had.

Thank you very much.
