Ubuntu 11.10, FF 11, ATI Catalyst v12.2, Driver Package version 8.95, WebGL doesn't work

  • 772

I'm running Ubuntu 11.10, FF 11, ATI Catalyst v12.2, Driver Package version 8.95, WebGL doesn't work.

This is a pretty capable setup and definetly did have FF work previously, Note: I've downloaded and installed the ATI drivers from AMD. Not sure how to get WebGL working.

    I have been able to get WebGL working by passing the aticonfig --initial command in the terminal. This is an installation step for the driver that I have initially missed.

  2. From a week of mindnumbing research on this matter (as it does affect me as well), webGL implementation under the Catalyst 12.2 drivers are either: A) Blacklisted somewhere else rather than the normal locations (i.e. about:flags) or B) Blacklisted for ATI x86_64 devices across the board. This would mean that Chrome devs need to change some code in default configuration outside of what is editable by users. I CAN seem to get webGL working in Firefox 11, but framerate is less than half of what I was getting in Chrome. I will say that after trying xorg-edgers latest gpu drivers (665 fps) vs. ati catalyst 12.2 fglrx(760 fps), I have seen quite an increase in framerate, and I really don't want to go back until I see evidence that xorg-edgers is comparable, but the functionality is definitely lacking ATM for certain applications. I just wanted to throw commiserating information out there in hopes that more people might be able to spark interest in a fix.

    I tried aticonfig --initial but the line didn't help the problem, even after reboot. I used the code to ignore the blacklist for hardware also, but with no success. I also changed about:flags in Chrome to the best possible configuration with no success. Is there anyone out there that has been able to solve this issue?
