AMD Radeon HD 7790 graphics/video card - how well will it work on Linux?
I got an AMD Radeon HD 7790 (MSI) graphics/video card. I was wondering: how good is support for it on Linux?
Will it even work? Are there any bugs? Will I be missing some features?
Like 3D acceleration, general performance, VDPAU, OpenGL support, CrossFire support, multiple monitor support - that kind of stuff.
How could I check whether the card supports these features once I'm running Linux?
The distribution doesn't matter, but I'd prefer Fedora or Archlinux.
I am also willing to use the proprietary driver, depending on which one works better.
Also, I found this page: http://support.amd.com/us/gpudownloa...eon_linux.aspx for the Catalyst driver on Linux. Does that driver support the 7790? Is it some generic driver? How does it differ than this "performance driver": http://support.amd.com/us/kbarticles...ceDriver.aspx?
I have been trying things on my 7790
Hi - I have a 7790, and have been trying to get it working well with MythTV, but don't have much success to report. The 7790 is 'Sea Islands' Bonaire, slightly different to the Southern Islands - support seems similar but they aren't identical. I've been using Ubuntu 12.04. I started out using Fglrx but removed it to go to the open-source solutions - the 2d playback with fglrx was fluid, but with interlacing quite visible. I updated the kernel to 3.10.9 and then 3.11.1 without too much trouble (card recognized and drm enabled in kernel). Updating to Mesa 9.2 from source went OK, but there were a few steps after that (adding things to ldconfig). MythTV could use vpdau in playback, but I don't think it was using the UVD2 module, but the CPU and 'softpipe'. UVD decode is (I think) working with older cards and may be working for the 7750/7770. Certainly CPU usage was high, and the visuals were not that good (interlacing was bad). Vdpauinfo only ever gave me an 'unable to find any nvidia' error.
Then I started adding repos (xorg-edgers, oibaf and others) and my problems began. I found I'd lost any dri, and then X, and then the command line. I probably don't know as much as I should to be using the -RC kernels. For all I know I could have been one simple config step from really excellent performance on the 7790 hardware (which should have abundant horsepower really). I suspect the October release of Ubuntu and the November release of OpenSuse will probably go close to optimal performance.
I now have Suse 12.2 set up, but the kernel (3.5.) and mesa (7.) are quite old. Performance at the moment is not great, but that's probably because the graphics card is an unknown quantity to the older software. I'm away from home atm so I can't get at my system. This is probably not very informative.
