[SOLVED] Chrome Video Corruption-KDE-ATI-64bit
Posted: Feb 16th, '14, 22:34I am posting the solution here because of the confusion that may be caused by trying to follow the thread for the solution, but you may want to read the thread to see more about what the problem was. I have an ATI Radeon 6870 and 64 bit Mageia. I think you need to create the link shown below on a clean Mageia 4 install.
It seems uninstalling/re-installing the Mageia fglrx drivers fixes some of my problems, but you have to add a symbolic link from /usr/X11R6/lib64/modules/ to /usr/lib64/dri/ where fglrx_dri.so is actually installed, or you'll get this error when you run Chrome in konsole:
It was this slow indirect rendering that was causing my main issues. Also running this will give you a better clue to the problem:
So uninstall the fglrx package and re-install it. I don't know why mine weren't right.
Then open a console as root and make a symbolic link to the proper location like this:
Now when you run google-chrome from a terminal the above error shouldn't be present and other things explained below will work properly. Again, I don't know if this is a common problem or a glitch on my system, but running Chrome in a terminal will still let you check for errors if you have a problem.
Below is the original post and information about how I came to this solution, and there was a sound issue that was fixed also but I didn't notice that causing a problem.
Original post and information:
I posted the fix for this in basic support but I don't believe it is fixed or has came back with updates, and I believe it has to do with the video driver or video options in Chrome.
Sometimes when you have more than one tab or when you open another program like Kwrite you get flashing, other pages showing through etc. Minimizing the programs sometimes clears it up, but not always. Sometimes you have to close them all.
I have changed Chrome options with chrome://flags and chrome://plugins but nothing seems to fix it. Also, it never happens unless Chrome is running.
I think it may be a Chrome setting relating to video but I can't isolate it. I've tried enabling/disabling hardware acceleration and other things like pepper flash and can't find the right combination of settings to fix it, if there is one. I'll try and find a combination of pages and apps that causes it and post that but it seems random.
Any ideas?

libGL error: reverting to (slow) indirect rendering
It was this slow indirect rendering that was causing my main issues. Also running this will give you a better clue to the problem:
- Code: Select all
[john@localhost ~]$ LIBGL_DEBUG=verbose glxinfo > /dev/null
libGL: AtiGetClientDriverName: 13.25.5 fglrx (screen 0)
libGL error: OpenDriver: failed to open /usr/X11R6/lib64/modules/dri/fglrx_dri.so, error[/usr/X11R6/lib64/modules/dri/fglrx_dri.so: cannot open shared object file: No such file or directory]
So uninstall the fglrx package and re-install it. I don't know why mine weren't right.
Then open a console as root and make a symbolic link to the proper location like this:
- Code: Select all
ln -s /usr/lib64/dri /usr/X11R6/lib64/modules
