Hi everyone, i have been running Ubuntu 5.04 on my Sony Picturebook C1MHP for many months now, everything works nice Jog Dial, Bluetooth, Suspend, just the camera not working but that's useless anyway.So, decided to upgrade to 5.10. What a disaster!, Nothing worked anymore..most importantly, everything was really slow...especially boot time.So i decided to upgrade to 6.06.RC WOW really nice..everything works..boot time good too BUT and it's a big BUT , after running for a while the whole thing just freezes! The only waay to get out of the freeze is to hold the power button down and reboot. In addition to this some of the application buttons (Close, Next) have lines on them, when i hover the pointer over them they clean up (wierd huh?)FYI i have 6.06 RC running on an IBM X21 and so far it's been a dream.So..anyone know why 6.06 RC freezes?In the mean time i have had to re-install 5.04 as it's the only version that seems to work. Every other version seems to be going backward not forward.
