Hi,
I have Nvidia Quadro NVS 440 with four 1280x1024 LCD monitors and I´ve tried to upgrade Kubuntu from 9.10 to 10.04. Everything works well at 9.10. After upgrade, system is hanging and I cannot reach desktops in all monitors. I´ve tried to reconfigure x server using Nvidia-settings control panel. This doesn´t work. So i tried to reinstall system from CD, because there should be something wrong with the upgrade, but the problem persist. I´ve tried to reinstall with Ubuntu, but there is same problem. My configuration of screens are: Screen 3 left of Screen 0, Screen 0, Screen 1 above Screen 0 and Screen 2 right of Screen 1, separate X screens and Xinerama enabled. Sometimes, if i reach upper edge of Screen 0, mouse will continue at the lower edge of screen 0. Screen 3 is not reachable and If I try to move mouse to it, system will hang and x server is automaticaly restarted. I´ve tried to configure all screens with absolute positioning too, but this doesn´t work either. My only option now is downgrade to 9.10 :(. So is there someone, who can help me? Thanks a lot.

first thing to check: system admin hardware driver, is yours activated ?

you might add this ppa to your sources.list:

when users use a previous xorg.conf, lucid often complaint as kernel now do the job (by default xorg.conf is not needed), so save yours or rename it (in case ) and erase the actual one, then reboot and run again nvidia-settings

sudo update-pciids && update-usbids

Thanks,

but i did a clean install too and problem is the same (at KUBUNTU and UBUNTU). Xorg.conf deletion and reconfiguring didn´t work. Do You have any other idea, please?

Thanks.
