Hellow fellow linux nerds, this is my first post and I'm in dire need of a guiding hand.
Let me first say thanks to phoronix, I found out about this researching for my new PC rig, its hardware test comparison helped me choosing this ATI r7 260x card, which correct me if I'm wrong, but seems pretty good.
But I do still need some help as the Catalyst driver is pretty bad documented and hard to deal with.
I'm on Debian Jessie, tried out smxi scripts and ended up with 3.15 liquorix kernel, 14.4 Catalyst from AMD.
Actually the mesa driver seemed pretty good and stable, I'm just trying out the catalyst driver, since its reported to get the best performance from games and such.
The first issue I'm having is of course underscan, this apparently reported by several others, its giving me a really hard time to deal with, the normal solution:
isn't persistent, every time I set this, reboot a look back at the pcs file, the entry is missing, actually only now I've successfully used this, quitting X environment, setting it, starting X again.
But I don't really know if this will persist.
Besides that, the only way to fix this was:
Which also isn't persistent, not even when the screen goes blank. And one can see how annoying this could be.
Second issue is about the card performance. Until now I've only been able to test it once, the game looked pretty good but had some hang ups, which is a MAJOR let down.
Apart from that, I was seeing some artifacts, which I just found out are caused by vertical tearing. Adjusted this setting, lets see how it does.
I would also like some suggestion of game that can showcase the power of the card, just to test it out.
Finally, the other issues are just things to hammer down and get things working perfectly.
Audio coming from the HDMI port is really garbled , audible but bad, was the same from the mesa driver. Would like to get it working or to just disable it completely.
My display apparently has this DDC/CI feature, pretty wide range of backlight brightness, I would like to try to control it via software, with xbacklight or ddccontrol.
And finally again, I would like your opinions if I should stay with the catalyst, try on the open-source or fully go for the catalyst beta 14.6
Thanks, I know this is a lot of stuff I'm asking in, any input is appreciated.
