[Bug 475428] Re: font corruption with xserver-xorg-video-ati driver
I have a Gateway LT3114 notebook with an AMD64 processor and ATI graphics. I am experiencing this same corrupted fonts bug. I actually have two LT3114s, and both of them do the same thing, and it does not seem to matter which release I try. I was running 10.04 LTS, but decided to try 11.04 in one of my LT3114s, but there was no difference. I also tried 10.10, and saw the same thing. This randomly corrupted font thing can happen while I am viewing a web page. I seems to happen a few seconds after the page initially loads, which makes me think this is somehow provoked by something a script in the page is doing. Some web pages are almost guaranteed to clobber the font memory. However, I can also clobber the font memory simply by scrolling too quickly through a PDF document. Is there some way in which I can replace the defective driver that comes with the Ubuntu distro with one that does not cause this font corruption? I am something of a newbie, and would like to have a step by step procedure I can follow to remedy this situation, because power cycling my machines frequently just to be able to read the screen is getting old. I have tried to be an Ubuntu evangelist in my company, but this is a Show Stopper that has caused me no end of grief. And needless to say, I will not be able to convince my co-workers to abandon MicroSloth in favor of Ubuntu with stuff like this going on in the software that is reputed to just work making my own work difficult. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/475428 Title: font corruption with xserver-xorg-video-ati driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/475428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 475428] Re: font corruption with xserver-xorg-video-ati driver
I have tried another FOSS distro -- Trisquel 4.5 in my LT3114, and it does not exhibit the font corruption bug, no matter what I do, so it looks like the driver included in the Trisquel 4.5 distro (also FOSS) does not use the same defective code as is included with Ubuntu. I suggest someone should try the ATI driver from Trisquel (64 bit, as that is what I am using in my LT3114s) with the rest of the Ubuntu distro, to see if the driver from Trisquel solves this problem, because if it does, that should be an easy substitution. The resulting Ubuntu should Just Work again, and I can resume evangelizing for Ubuntu Linux over MicroSloth anything. Please keep me posted on this. While I am not a coder or a hacker, I hope the above is useful to those who are. P.S. This message came from my LT3114 running Trisquel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/475428 Title: font corruption with xserver-xorg-video-ati driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/475428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This looks like download from screen bug.
