If you have one of these cards, you do have the option of using the Catalyst Legacy driver, but only if you downgrade your Xserver version (the Catalyst Legacy driver does not support the kernel version (3.5) or the Xserver version (1.13) that Ubuntu Quantal/12.10 uses).

If you have one of these cards, you do have the option of using the Catalyst Legacy driver, but only on Ubuntu 12.04/Precise and earlier. The Catalyst Legacy driver does not support the kernel version (3.5) or the Xserver version (1.13) that Ubuntu Quantal/12.10 uses.
This can be done really easily by following the instructions given at [[https://launchpad.net/~makson96/+archive/fglrx]]. This PPA downgrades the Xserver and install a patched version of fglrx that supports kernel version 3.5 of Ubuntu Quantal.

1. Mac has the codecs mp3 ready inalstled and if something is missing you wont get any philosophical crap talk  just install the missing ones.2. Flash support  yeah, via a wrapper system that sometimes goes haywire  Also has problems with some drivers and compositing.3. OmniGraffle. There is absolutely nothing equivalent for Linux. It is alone good enough reason to switch to Mac.4. iTunes (the web shop) included. Really works. People do care about this, as iTunes is a rather well working concept and hassle free for the users. Plus, the iPods have sold plenty.5. Polished image. Open source projects have no idea of how to polish the final product. For instance the startup sequence of most distributions is plain horrible. Screen resolution changes (monitors pop up information boxes and flicker), color themes change, text in traditional text mode passing by,  Yuch. small things like that really do matter.6. Better IM clients. For instance Pidgin is just plain usability disaster. Been waiting for the Telepathy based applications to replace it for years now, but it seems to take ages. (Integrating seamless high usability communications tools for both home and corporate environments would be THE killer feature of the Linux.)7. You can get Office 2008 for Macs. The user interface is very usable, and it allows the user to focus on the content creation instead of fiddling manually with the formating tools for endless hours to create something actually good looking. OpenOffice does not manage that. They even dropped the ball entirely for 3.x, the test versions are just as horrible as 1.0 was in usability terms. (That is especially shame as there IS a complete redesign of the interface available. It is more usable, looks better, slightly original, and extremely well thought. It's called Flux by the way. But nothing like it will land before 4.x, which will take some 5 years lol)
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that's not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:
 
 
 
Section "Device"
 
  Identifier "ATI radeon 6870"
 
  Driver "fglrx"
 
EndSection

שמתי לב לתופעה מעניינת  מערכת ההפעלה מתעלמת מבקשות להרצה יזומה של fsck כאשר לפטופים עולים ללא חיבור למקור חשמל. מאחר ואצלי הלפטופ כמעט תמיד עולה ללא חיבור לחשמל, ובהפעלות האחרות שלו הוא יוצא ממצב standby (שכמובן לא מריץ את הפקודה היזומה), מתפספסות לי הרצות של fsck. לא שאני אומר שזו לא ההתנהגות הרצויה, אבל כדאי לשים לב לזה כאשר מתעסקים עם Force fsck on next reobot.
If you have a dual monitor display (also known as "Big Desktop"), use:
 
sudo amdconfig --initial -f
 
sudo amdconfig --set-pcs-str<nowiki>=</nowiki>"DDX,EnableRandR12,FALSE"
 
This was confirmed in http://phoronix.com/forums/showthread.php?t=18553. Be advised that you may need to manually set the correct refresh rate for your second monitor through catalyst.
