==X Server Related Issues==
=== No high-resolution video modes available ===
* Versions of the fglrx driver following 7.12 had problems with video resolutions higher than 1280 x 1024. The modes of the xorg.conf are simply ignored, and the server starts up e.g. with a resolution 1280 x 1024 (even if this resolution is not defined in xorg.conf). This is particularly a problem on LCD displays.
* [http://ati.cchtml.com/show_bug.cgi?id=160 This bug] documents the problem; it is '''fixed''' since driver version 8.2
* Looks like it reappeared again some version above ati-driver-installer-8-12-x86.x86_64.run . Version ati-driver-installer-9.2-x86.x86_64.run, and ati-driver-installer-9-4-x86.x86_64.run has this bug. At least on integrated HD3200 card.
=== No XVideo support on 690G integrated graphic chipset ===
*Upgrade your BIOS if you get random flicker lines and black screen with a 690G chip.
*Motherboard using the 690G IGP chipset don't have XVideo support. When you execute the "xvinfo" command you get "no adaptors present". This is the case by using the 8.39.4 FGLRX driver and whenever the "sudo aticonfig --overlay-type=Xv" command or the "sudo aticonfig --overlay-type=opengl" was used. ATI seem to know this as there list TVtime as an application unable to run on a 690G chip.
* XVideo works with 8-1 release (version 8.45.4).  You need to change the defaults in /etc/ati/amdpcsdb (created by amdcccle, loaded by X on start, and saved on exit). With X shutdown, set VideoOverlay=Son, OpenGLOverlay=Soff, and Textured2D=STrue. (Don't use aticonfig or xorg.conf to set these.  At this time, aticonfig and amdccle don't change these settings, and /etc/ati/amdpcsdb seems to override xorg.conf) (Verified on Asus M2A-VM with BIOS 1501)
* With 8-3 release (8.47.1), to get XVideo working I added ''Option "TexturedVideo" "true"'' to the xorg.conf file. It wasn't necessary to edit the /etc/ati/amdpcsdb file as described in the paragraph above; the open GL overlay can be active and it will still work.
=== System lockup on logout or switch to virtual consoles ===
If your system locks up after you logout or when you try to switch to a virtual console, this might be an instance of [http://ati.cchtml.com/show_bug.cgi?id=330 this bug]. It is likely that the problem only occurs for users with an '''Xorg version of at least 7.0'''. Probably it only affects users of '''DVI'''.
There is a workaround: Use a standard D-Sub VGA connector instead of the DVI connector.
This workaround was posted as a comment to another related bug: see [http://ati.cchtml.com/show_bug.cgi?id=239#c48 here].
Unfortunately "D-sub" users (like me) have the same problem.
=== BigDesktop (Dual screen) doesn't work after GDM login screen ===
This can occur on Ubuntu Feisty Fawn & Gutsy.
System > Prefrences > Screen Resolution
Select the resolution that is a combination of both screen resolutions wide and your height.
If X crashes during login, go to a virtual console using Ctrl+Alt+F1, log in, <code>sudo vim /etc/X11/xorg.conf</code>, and comment out the line which looks like the following:
{{Box File|/etc/X11/xorg.conf|
<pre>  Option  "DesktopSetup"  "something"</pre>
=== Computer Freezes while using fglrx (UMA and SIDEPORT)  ===
If after choosing fglrx as your driver in either xorg.conf or xfree86.conf files, the computer freezes and becomes unresponsive while trying to start X this may be the solution.
Some ATI cards have the ability to run in three modes: UMA, SIDEPORT, or a combination of both. UMA mode is that one in which the video card does not use its dedicated memory, but rather uses and shares the system memory. On the other hand, SIDEPORT mode is the one in which the card uses its own dedicated memory. And finally, the third mode is a combination of the previous modes in which the card uses both the system memory and its dedicated memory.
If your computer hangs, this settings may be where the solution lies. If your computer hangs, try using either UMA by itself or a combination of both. However, if you choose the combination, make sure that the UMA one is at least 128MB. In my case, I have SIDEPORT 128MB and 128MB UMA. If I choose any less for UMA, it does not work. This is definetly not an attractive solution since it compromises your systems performance. Hopefully, this will be solved very soon.
On some systems, the BIOS screen may not offer a choice of UMA or SIDEPORT.  In this case, you can try turning the amount of RAM dedicated to the video card down, from 128Mb to 64Mb for example.
=== Graphical Anomalies ===
This was experienced with an ATI Radeon X1600 Pro 512mb:
After following instructions for both Method 1 and Method 2, whenever the Composite Extension is disabled, the display would be almost unusable, but the fglrxinfo command would display the correct information.  If the Composite Extension is re-enabled the display would be usable, but fglrxinfo would report using mesa drivers.
To resolve the problem it maybe needed to lower the AGP Aperture setting in my BIOS to 128mb (or lower worked too).  The AGP Aperture was initially set to 256mb. After setting the AGP Aperture to 128mb, everything worked perfectly; the Composite Extension is disabled, fglrxinfo reports the correct drivers, and direct rendering is enabled. Some systems may require setting the AGP Aperture to the highest setting (256mb or 512mb).
There's been a bug report regarding [https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/150627 anomalies in Firefox] as well.
=== OpenGL framebuffer Corruption ===
This problem has been experienced on Thinkpads (T60p) with an ATI MOBILITY FireGL V5250 running driver versions 7.12, 8.01 and 8.02. Whenever any OpenGL application is rendered, the rendered output appears "scrambled" and unreadable. This problem is not very well documented and both glxgears and fgl_glxgears display this anomaly when testing.
When Anti-Aliasing is forced, the problem resides.
A solution (tested with 8.02 on Ubuntu Gutsy) to this problem is to open the ATI/AMD Catalyst Control Center and expand the item labeled '3D' in the options tree on the left-hand side of the window. From there, select "Anti-Aliasing" and check the box which reads: "Override application setting". Apply the settings and close the control center.
For an example of this anomaly, please see [http://i31.tinypic.com/244z9z8.png this image]
This solution not work on acer laptop with ATI Mobility Radeon HD 2400 XT.
=== Blank Screen with Xorg 1.3.0 ===
If you happen to get a blank screen on X startup and you find lines similar to those in your Xorg.log:
{{Box File|/var/log/Xorg.log|
2: /usr/lib64/xorg/modules/drivers//fglrx_drv.so(swlDalHelperValidateModeFromDAL 0x549) [...]
3: /usr/lib64/xorg/modules/drivers//fglrx_drv.so [...]
4: /usr/lib64/xorg/modules/drivers//fglrx_drv.so(atiddxPreInit 0x8b3) [...]
Then you're probably using the ati-drivers with Xorg-1.3.0. If that's the case the only solution (known to me) is to use a version < 1.3.0.
Edit: I got the same problem after using the --add-pairmode argument of aticonfig (using Xorg 1.3.0). My ati mobility x300 seemes to try
sending the monitor signal to the vga output (even if no monitor is connected to it). After pressing [Fn]+[F8(CRT/LCD)] the monitor
signal sometimes returnes to the internal laptop monitor.
By switching to a console or shutting down the X-server, the card switches back to vga...
My solution: overwriting the file /etc/ati/amdpcsdb with /etc/ati/amdpcsdb.default (sudo cp /etc/ati/amdpcsdb.default /etc/ati/amdpcsdb)
and restore the xorg.conf (since Xorg replaces /etc/X11/xorg.conf with a failsafe config file). Then reboot the system: fglrx should now
work fine again with Xorg-1.3.0 .
=== Radeon GPU fan is very loud / constantly works ===
:See [http://ati.cchtml.com/show_bug.cgi?id=499 bug 499] for additional information.
It seems fglrx has a bug with all X800/X850 cards causing them to heat up excessively
even when not in 3D mode. This behaviour will cause the cards' fans to function on full
blast continuously. There is no known fix as of driver 8.31.05 or previous. Open source
"radeon" driver does not exhibit this problem.
My Ati 1650GT has the same problem.It was normal when I enter ubuntu for 1 or 2minutes,and than ,the fan became crazy..No doubt it's because the temp~
It happens too with Radeon X1800 GTO and Radeon X1900 GT.
Possible solution (at least using a Mobility Radeon X1600):
<pre>aticonfig --set-powerstate=1</pre>
To find out which powerstates your Radeon supports try:
<pre>aticonfig --lsp</pre>
=== System freezes after logout with GDM, KDM or XDM<ref>http://ati.cchtml.com/show_bug.cgi?id=239 Going back to gdm/kdm/xdm hardlocks after running X session</ref> ===
If you use GDM, which is the default Login Manager on Ubuntu, modify
<pre>sudo gedit /etc/gdm/gdm.conf</pre>
{{Box File|/etc/gdm/gdm.conf|
If you use KDM, which is the default Login Manager on Kubuntu, add to the [X-:*-Core] section the following
<pre>sudo kate /etc/kde3/kdm/kdmrc</pre>
{{Box File|/etc/kde3/kdm/kdmrc|
if you use xdm, add the following to
<pre>sudo gedit /etc/X11/xdm/xdm-config</pre>
{{Box File|/etc/X11/xdm/xdm-config|
<nowiki>DisplayManager*terminateServer: true</nowiki>
=== System freezes at startup of Fedora 7 or RHEL 5.3 after installing the driver ===
Turn off the Redhat Graphical boot from grub config:
Edit the grub config file located at /boot/grub/grub.conf and remove the 'rhgb' from the kernel line in order to disable the Redhat Graphical boot.
This also works for Red Hat Enterprise Linux 5.3.
=== System lockup on logout with catalyst 8.01 <ref>http://www.phoronix.com/forums/showthread.php?t=7448&page=5 System lockup on logout with catalyst 8.01</ref>===
To solve this issue you need to disable atieventsd. On ubuntu you can run:
sudo /usr/sbin/update-rc.d -f atieventsd remove
=== Intermittent Freezes/Lockups due to AGPv3 running at 8x ===
Try forcing X to set AGP Speed to 4x
{{Box File|/etc/X11/xorg.conf|
<pre>  Option "AGPv3Mask" "0x00000002"</pre>
((Would be nice to put down WHERE to change this, not just to change this. The same applies to just about every hint shown above.))
+ You add it to the "Device" section for your graphics card in /etc/X11/xorg.conf.
=== Flickering Video with Compiz enabled ===
Flicking video using mplayer to play movies may be caused by Compiz.  Compiz is enabled by default on new Ubuntu 8.10 installs (and other?).
To disable Compiz in Ubuntu:
# right-click on the background, select "Change Desktop Background"
# Select "Visual Effects" tab
# Select "None"
(Verified to work on Ubuntu x86_64 8.10 with HD 3200 and Ubuntu x86_32 8.10 with XD 2300)
