You certainly have some agreeable opinions and views. Your blog provides a fresh look at the subject.
 
== Introduction ==
 
This guide should help you install and configure the proprietary graphics drivers from ATI. This guide applies for ALL versions of fglrx - it was made before the (rather dramatic) 8.8.25 January 05 release, but it is maintained such that all versions should work.
 
*Note:  If you are using an ATI 7500 Mobility (or such card that isn't supported by the ati-drivers) this HOWTO will not help.  Instead use the ATI kernel drivers. See also: http://forums.gentoo.org/viewtopic-p-2137276.html#2137276
 
== Kernel Configuration ==
 
Get into menuconfig (cd /usr/src/your-kernel && make menuconfig) and check the following:
{{Box Code|menuconfig|<pre>
Loadable Module Support --->
[*] Enable loadable module support
  [*]  Module unloading
 
Processor type and features  --->
[*] Enable VM86 support
[*] MTRR (Memory Type Range Register) support
 
Device Drivers --->
Graphics Support --->
  <M> /dev/agpgart (AGP Support) 
    <M> Your_AGP_Chipset_Here
  [ ] Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
 
Graphics support --->
  [ ]  Support for framebuffer devices
 
Kernel Hacking --->
  [ ] Kernel debugging
</pre>
}}
Sync your kernel menuconfig with the selected portions posted here. (note: you can compile /dev/agpgart & your agp chipset [most likely ati-agp] into the kernel if you want.)
 
'''Please be aware that -mm and -rc(1,2,3,4,...) kernels often break fglrx due to unexpected changes in syntax, etc. If you want to use ati-drivers, use the stock gentoo-sources or at the very least, a STABLE 2.4 or 2.6 kernel!'''
 
Don't forget to compile, install, and reboot into the kernel. Directions for this are beyond the scope of this file; if you need help recompiling the kernel, [http://gentoo-wiki.com/HOWTO_Compile_a_Kernel_Manually click here].
 
== Grabbing a Driver Set ==
 
For installation it will be easier to drop out of X to a command prompt. Do this using whatever command your Window Manager uses.
I use fluxbox so it's just rightclick -> fluxbox menu -> exit. For KDE or GNOME it's probably just a matter of logging out. When all else fails, hit CTL+ALT+BACKSPACE to kill the X server ungracefully. If the X server only reboots or for some reason you've disabled this hotkey, log in as root and type '''init 3''' to bring the system run level down.
 
There is also the possibility to stop the xdm service by entering ''/etc/init.d/xdm stop'' as root.
 
Thanks to portage, installing the drivers is easy. If you have not already done it recently, start by synchronising your portage tree:
 
emerge --sync
Getting the latest drivers will probably mean unmasking them.
 
echo "x11-drivers/ati-drivers ~arch" >> /etc/portage/package.keywords
echo "x11-drivers/ati-drivers-extra ~arch" >> /etc/portage/package.keywords
 
Replace {{Codeline|<~arch>}} with your system architecture; it's going to be either {{Codeline|~x86}} or {{Codeline|~amd64}}, the only two CPU architectures supported by the ATI driver.
 
Now let's install the drivers. ati-drivers-extra is a (god-awful) control panel for the driver you probably won't use; you can leave that part out if you want, but for completeness we mention it here.
 
su -
emerge -av ati-drivers ati-drivers-extra
 
The next step is switch to the ATi OpenGL subsytem:
 
(#opengl-update ati)
eselect opengl set ati
(very important!)(opengl-update is deprecated)
Configure X:
First, make a standard config file.
 
xorgconfig
 
For a single screen
 
aticonfig --initial --input=/etc/X11/xorg.conf
 
For a dual head, second screen is {left|right|above|below}
 
aticonfig --initial=dual-head --input=/etc/X11/xorg.conf --screen-layout={left|right|above|below}
 
Adapt input with your path to xorg's conf file
 
If for some reason this command doesn't work, then try manually executing from its default location:
 
/opt/ati/bin/aticonfig [...]
 
Now, let's get back into X.
 
startx
 
Open up a command prompt and run:
 
glxinfo
 
If the OpenGL vendor string says "ATI Technologies," then congrats! You've got the drivers working and hardware acceleration going great. If not...read on...
 
== Troubleshooting ==
 
=== Config Files ===
By default, the driver uses the Internal AGPGART. Sometimes the internal one doesn't work, and you will have to use the one provided with the kernel. Search your xorg.conf for the line that has the option "UseInternalAGPGART." Simply change the "yes" to "no."
 
{{Box File|xorg.conf|
Option "UseInternalAGPGART" "no"
}}
 
 
Now simply add the modules to {{Filename|/etc/modules.autoload.d/kernel-2.x}} where x is your kernel version.
 
Add the following (ORDER IS VERY IMPORTANT);
{{Box File|/etc/modules.autoload.d/kernel-2.x|
agpgart
intel-agp # change intel-agp to your chipset. eg: via-agp, nvidia-agp sis-agp.
fglrx
}}
 
Finally, run
 
modules-update
 
Then you can reboot and everything should work. If you have are having problems, check dmesg and /var/log/Xorg.0.log for more info.
 
=== Blank screen or monitor turning off after startx ===
 
Versions of ati-drivers >= 8.16.20 (and probably <= 8.20.8) have an issue with this that's easily corrected by inserting:
{{Box File|xorg.conf|
    Option "ForceMonitors" "notv"
}}
in the device section of xorg.conf (discussed here: http://bugs.gentoo.org/show_bug.cgi?id=103028)
 
 
Check if you have a non-DDC monitor connected via VGA/HD15 connector. If so change your xorg.conf:
{{Box File|xorg.conf|
#  Option "DesktopSetup"              "0x00000000"
    Option "MonitorLayout"              "NONE, CRT"
    Option "IgnoreEDID"                "off"
    Option "HSync2"                    "30-85"
    Option "VRefresh2"                  "50-160"
#  Option "ScreenOverlap"              "0"
}}
where HSync2 and VRefresh2 are your monitor parameters.
 
 
Also, try changing the MonitorLayout option. The default is "AUTO, AUTO", which is to say X will attempt to autodetect what kind of monitor you've got on the first and second display heads. This can theoretically fail (though I have never observed it). Try changing it around a bit. For example, if you have an LCD and no secondary monitor, change the line to read:
 
{{Box File|xorg.conf|
    Option "MonitorLayout"              "TMDS, NONE"
}}
 
if you have a CRT, simply replace "TMDS" with "CRT".
 
=== Crashes on startup ===
'''If you are unable to use any 3d applications and get this error instead:'''
 
FGLTexMgr: open of shared memory object failed (Function not implemented)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!!
FGLTexMgr: open of shared memory object failed (Function not implemented)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!!
FGLTexMgr: open of shared memory object failed (Function not implemented)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
 
'''Then you do not have tmpfs mounted on /dev/shm, which the driver requires.''' Make yourself sure you have tmpfs support compiled into kernel. It's under
 
    File systems -->
        Pseudo filesystems -->
            [*] Virtual memory file system support (former shm fs)
 
To mount this, add to following line to {{filename|/etc/fstab}} (if it isn't there already):
 
{{Box File|/etc/fstab|
tmpfs    /dev/shm          tmpfs        defaults            0 0
}}
 
Then just do a:
mount /dev/shm
 
If the drivers still crap out on you, or for example you get a black screen on X init, try going into your system BIOS and change graphics-related stuff around. Believe it or not, for me my 9800 gives a black screen on X init if I have the AGP Aperture set at anything other than 128MB. I don't know what causes this, and I don't care; I'm just relating to you how I overcame ''my'' problem ;)
 
Also, '''whenever you update your compiler''', you '''must''' recompile your kernel otherwise you won't be able to insert the fglrx module. Note that recompiling your kernel means you must also unmerge/emerge ati-drivers!
 
=== Duplicate symbol errors in X log ===
If you are unable to start X or X fails to load the fglrx driver and you have multiple symbol errors in your Xorg log, chances are that you have compiled X with the ''dlloader'' flag.  This flag can not be used with the fglrx driver.  To fix this problem, remove the dlloader flag by editing your /etc/portage/package.use file as follows:
{{Box File|/etc/portage/package.use|
x11-base/xorg-x11 -dlloader
}}
Now re-emerge the ''xorg-x11'' package and reinstall the fglrx driver.
 
=== Crashes on the exit of X.org / X won't shutdown ===
Perform the following if you can get the fglrx drivers working with hardware acceleration, but are suffering from a complete system crash when trying to quit X. You should boot into your system, login, then start on this. You don't need to boot into X, and shouldn't need to edit your xorg.conf file (as fglrx is already setup as the driver and working)
 
You've emerged the "stable" version of the ati-drivers, these are out of date -- remove them (emerge --unmerge ati-drivers), to add the most recent you should either add them to the keywords file (/etc/portage/package.keywords) or emerge your local ebuild (emerge /usr/portage/x11-drivers/ati-drivers/ati-drivers-8.22.5.ebuild) if you're told it requires a dependency, emerge the local e-build for that, then try again. (usually eselect-opengl is required.)
Once you have the most recent ati-drivers emerged, run (eselect opengl set ati). Now you can (startx) and hopefully quit without any problems.
 
 
=== glxinfo says "error: failed to open DRM: Operation not permitted"  ===
If a check with the glxinfo fails for ordinary users though works fine for root it might be related to filepermissions of the device-file.
Here is how to solve it:
 
Make sure that the filepermissions on the card-device allows the video-group to read and write. The common group in gentoo with X is "video". All normal users should be part of this group. Also, the device must have permissions for this group to read and write the card-device.
 
Check the permissions on the card-device:
 
<pre>
root:/#ls -lcF /dev/dri/card0
crw-rw---- 1 root root 226, 0 Oct  5 16:19 /dev/dri/card0
</pre>
 
It can be changed with:
 
<pre>
root:/dev/dri#chgrp video card0
</pre>
 
Check if user is part of video:
 
<pre>
paddlaren:~>id paddlaren
uid=1000(paddlaren) gid=1000(paddlaren) groups=1000(paddlaren),10(wheel),11(floppy),18(audio),19(cdrom),80(cdrw),85(usb),100(users),35(games)
</pre>
 
To add a user to the video-group:
 
<pre>
root:~#gpasswd -a my_user video
 
paddlaren:~>id paddlaren
uid=1000(paddlaren) gid=1000(paddlaren) groups=1000(paddlaren),10(wheel),11(floppy),18(audio),19(cdrom),27(video),80(cdrw),85(usb),100(users),35(games)
</pre>
 
Logoff and on to ensure that the membership of the group is known to the system.
