I can't offer a real fix, just a shot in the dark suggestion and some
information as to my own system performance.
Suggestion: Maybe consider backing up fully, then upgrade to Jessie.
If you try Jessie, I'd go with 64 bit, not 32.
Info: I'm running Jessie. KDE but I also have Gnome installed as a GUI
back up and for the Gnome tools that it adds to the KDE menu.
When I run GLX gears I get the same message regarding frame rate that you
do. But my actual frame rate is nothing like the refresh rate. 60Hz
refresh, but GLX is about 2800 FPS.
System hardware specs are:
Four year old Dell Inspiron 530, with Intel Core2 Quad processor Q8200
"Yorkfield" 2.33Ghz, 8 GB RAM.
Video card: Asus Nvidia GeForce ENGT430 1GB DDR3 (after market card one
or two years old)
Monitor: Samsung Syncmaster 24" @ 1920x1200 @ 60Hz
I'm running the nouveau open source driver, not the Nvidia driver.
GLX Gears reports:
$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
13479 frames in 5.0 seconds = 2695.692 FPS
