I think i finally fixed it! I need to create a xorg.conf file and add set the correct driver to radeon. it was fbdev before. Section "Device" ### Available Driver options are:- ### Values: <i>: integer, <f>: float, <bool>: "True"/"False", ### <string>: "String", <freq>: "<f> Hz/kHz/MHz", ...

I think I'm starting to get what happened. One of the answers on the page you linked to tells you to run this: cd /usr ; sudo ln -svT lib /usr/lib64 That will i) move you into the /usr directory and ii) create a link called lib64 (which will be /usr/lib64 if you run the ln command in /usr) pointing to /usr/lib. The command should not be ran as your admin ...

A generally good experience. I did have KDE problems (some minor crashes, really rarely) with my Radeon 7870, but this never happened on Ubuntu with Unity. Installing the driver is pretty straightforward. I used the AMD installer to generate the .deb files and installed them by hand. Then I generated the config file with (aticonfig --initial), and ...

First download the ATI binary driver for linux, If you do ./ati-XX.run --help you could see a lot of options, IIRC, there's an --extract option that will extract everything inside to a folder, which contains: Kernel module (fglrx) source code fglrx opengl library (binary)

The firmware for your graphics card is missing. You have to explicitly install firmware-linux-nonfree from the non-free repository. Add the non-free repository to /etc/apt/sources.list (or /etc/apt/sources.list.d/) Run apt-get update as root Install firmware-linux-nonfree with apt-get install firmware-linux-nonfree You probably have to reboot after this ...

There are some minor issues with AMD's proprietary drivers. They are missing a key protection routine (robust shaders) so you can't run WebGL or OpenGL Shader CSS without risking exploits. (These are turned off in Chrome if you have an ATI card.) Flash has stopped supporting 3D acceleration altogether in Linux due to security exploits. Hopefully they ...

Mint has its own tool to install propitiatory drivers, I recommend you use it. I haven't used Mint in a while but if memory serves, it should be available in the menu => control center => Additional Drivers. That should bring up a window like this one (taken from here): ...

There is a bug in the drivers. You have the correct driver info loaded. You need to go to /etc/modprobe.d/radeon-kms.conf and set it to this: radeon.modeset=0 Shut down and add the PCI card then go to BIOS and select the correct video adapter and save and reboot.

I'd like to add some information to the previous answer, since it covers basic support and functionality, etc. (I also agree regarding NVidia vs ATI). The performance will not only depend on the card you choose, but also whether you choose to use the Open Source drivers or the proprietary AMD Catalyst drivers. The difference between them is huge (about half ...

A closed source driver distributed by another channel won't be much different as one can't recompile it. However some kernel configuration and heuristic around the kernel module might be more targeted towards your distribution (dkms, compatibility settings, device id's, etc.). I strongly advice to use packages. It's much easier to uninstall it and it ...

I think the problem is poor color depth. The Windows graphics driver allows 32-bit true colour. The Linux ones (free or proprietary) don't. Sadly this means that for the time being I'll be going back to Windows.

What i would try: Download a "Live" version of a distribution like ubuntu, make 2 cds/dvds/usb-sticks and start both notebooks with them. Now you can make a side by side comparison, and you should see if it's linux or if it's a problem with the hardware of one of the notebooks.

You should check out Monica - it's a handy GUI frontend that let's you calibrate your monitor. Monica depends on fltk-devel AFAIK. Read the wiki article on color management under Linux. A little bonus (and one of my favourite monitor tools) is Redshift which is the Linux equivalent of F.lux. It sets the temperature of your monitor according to the position ...

As of right now, FGLRX graphics switching will not work on mbp 8,x model. The only way to use fglrx for your model is through BIOS emulation mode, and because of that it will not work. You can however get graphics switching to work on your model by setting up EFI boot. Doing so is not easy and requires a series of grub2/kernel patches. Instead of using ...

I don't think there is a device file with the fglrx driver but you can run glxinfo and fglrxinfo on both video cards and it should show a massive improvement over the onboard video card. With switcheroo there is a device file that can switch the wanted power state and the wanted video card. My onboard video card copy up to 50 fps to the video buffer when my ...

Every time I re-install the fglrx64 RPM, which is every time the kernel is updated, I need to re-run aticonfig --initial -v manually. In fact, it's on a post-it on my server. I do it at runlevel 3, dunno if that matters. This is on CentOS, which should be the same.
