Title: Changing graphics cards in Ubuntu Post by: Laereom on June 14, 2011, 01:38:40 AM I recently upgraded my 5770 to a 6950 in Ubuntu, and it isn't being recognized as an OpenCL device. Does anyone have any experience with similar situations or know what causes a new device to be 'seen' by OpenCL?
Title: Re: Changing graphics cards in Ubuntu Post by: supa on June 14, 2011, 04:41:02 AM You should be able to just swap cards. I do it all the time. Can you get glxinfo, etc working in x? That would suggest your driver isn't installed/loaded or your Xorg.conf is somehow wrong. lsmod | grep fglrx Do you get something? Did you update your Xorg.conf ? aticonfig --initial ? Title: Re: Changing graphics cards in Ubuntu Post by: Laereom on June 14, 2011, 11:55:31 PM Upon running glxinfo, I get a massive amount of output that's pretty meaningless to me.
Upon running lsmod | grep fglrx, I get: fglrx 2434640 173 Upon running sudo aticonfig --initial, I get: Uninitialised file found, configuring. Fail to link to fglrx-libglx.so, please check whether driver is installed correctly Using /etc/X11/xorg.conf Saving back-up to /etc/X11/xorg.conf.original-0 This last one seems interesting...the driver works fine for running the display. I basically just turned off the proprietary driver when after I put in my 6950, and then turned it back on; I did this the lazy way via the Additional Drivers menu. If these drivers aren't working for it, where exactly should I be getting them from? What source do you use for your drivers? Title: Re: Changing graphics cards in Ubuntu Post by: supermine on June 18, 2011, 05:20:51 PM I have the same problem. The solution that works for everyone is to install the propietery drivers from ATI - however their site is down! Anyone knows where to get the .run files except from the official ATI pages, which are down since a couple of hours?
Edit: Found the driver on another mining rig - so if you guys need the file as well, send me a PM. Title: Re: Changing graphics cards in Ubuntu Post by: vx609e on June 21, 2011, 02:19:58 AM I have a similar problem...if I change cards count (go from 2 to 3 let say), ubuntu does not boot anymore...I need to reinstall OS. That's really tedious...there's gotta be a quick fix.
Title: Re: Changing graphics cards in Ubuntu Post by: BitcoinRigs.com on June 21, 2011, 05:37:54 AM Whenever you change cards, do this:
Code: sudo aticonfig --adapter=all --initial -f Title: Re: Changing graphics cards in Ubuntu Post by: Sideways on June 21, 2011, 06:46:31 AM Also check your SDK version, the 6xxx cards are not supported by 2.1, you have to goto 2.4
