I am using a single-monitor 1280x1024 setup with a 256M FireGL V3700, and a similar issue is exhibited (differing only in log output). I have successfully used a dual-monitor setup with this card where _both_ monitors had higher resolution than this one; I agree that this is not likely to be cause

I cannot believe that this is really a memory issue. Yesterday I exchanged the hardware from a single monitor with 128MB nVidia graphics card to a dual monitor setup with a 256MB ATI Technologies Inc RV730 [FirePro V5700]. The user switching was working flawlessly with the nVidia proprietary driv
