RS485
lspci returns ATI Technologies Inc RS485 [Radeon Xpress 1100 IGP]. Splash screen bug #136582 affects release 7.10 but not 8.04.
Ubuntu 8.10 and later
Since Ubuntu 8.10 3D and desktop effects works out of the box with the open source -ati driver.
Ubuntu 8.04 and previous
The user can choose between two drivers: The open source -ati driver and the closed-source fglrx driver. Enabling 3D acceleration requires extra user configuration anyway.
Enable DRI -ati
Direct rendering has been turned off by default for RS48x/RS690 since revision 6.7.194 of xserver-xorg-video-ati due to missing features and unresolved bugs in the mesa library. The situation has changed with the release of Ubuntu 8.10, where DRI is supported out of the box. Ubuntu 8.04 users can update to a backported mesa package from Andrius Štikonas PPA and enable DRI in the driver shipped with Ubuntu 8.04. 1. Add these software sources and update your mesa packages.
deb http://ppa.launchpad.net/stikonas/ubuntu hardy main deb-src http://ppa.launchpad.net/stikonas/ubuntu hardy main
2. Add these options to respective sections in xorg.conf
Section "Device" Identifier "Configured Video Device" Option "DRI" "true" Option "GARTSize" "64" EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" EndSection
3. Restart the X server by logging out and back in, or typing sudo /etc/init.d/gdm restart
.
4. Check status flag
$ glxinfo | grep "direct rendering"
5. Check functionality by invoking glxgears.
$ glxgears
Enable DRI -fglrx
The proprietary binary driver produced by AMD/ATI is commonly known as fglrx. It can easily be installed using System->Administration>Hardware Drivers.
2. Restart xserver by logging out and back in, or typing sudo /etc/init.d/gdm restart
.
3. Check status flag
$ glxinfo | grep "direct rendering"
4. Check functionality by invoking glxgears.
$ glxgears
5.Change overlay type to Xvideo if video upscaling looks blocky.
$ sudo aticonfig --ovt=Xv
Desktop Effects
Desktop effects don't work by default up to Ubuntu 8.04. To make them work the user has to enable the Direct Rendering Interface and AIGLX with the open source driver as described above. The second alternative is to install the proprietary driver fglrx. 1. Enable Direct Rendering Interface or install fglrx 2. Enable AIGLX by adding options to xorg.conf
Section "Device" Option "XAANoOffscreenPixmaps" EndSection Section "ServerLayout" Option "AIGLX" "true" EndSection Section "ServerFlags" Option "AIGLX" "on" EndSection
3. Add this line to .config/compiz/compiz-manager
SKIP_CHECKS="yes"
4. Restart xserver by logging out and back in, or typing sudo /etc/init.d/gdm restart
.
5. Finally turn on desktop effects in menu Preferences>Appearance>Visual effects.
External monitor
External output works with open driver. Use xrandr
to configure. Display device hot plugging work, outputs must be configured manually. See driver|documentation for more information
