https://forums.opensuse.org/english/get-technical-help- here/applications/480831-xorg-high-cpu-usage-sluggish-performance-fresh- install-4.html Sometimes I see the EQ overflow errors in Xorg log, but not other times. Looked for a newer vbios for the GT240, but only found the same version I had http://www.techpowerup.com/vgabios/64154/EVGA.GT240.512.091114.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077616 Title: 10de:0ca3 (EE) [mi] EQ overflowing.
