apport information ** Tags added: apport-collected
** Description changed: I suffer from for a while of this beahvior. Everething was perfect in Ubuntu 11.04. Since 11.10 (now with 12.04 still in development) I have a random freeze on my desktop. Everything on the system runs fine, and then after a while, 30-40-80 minutes the whole system locks. First time, I was still able to move the mouse, but unable to click on anything. Subsequent times, no response from mouse or keyboard, and mouse pointer is gone. Sometimes I can switch ctrl+alt+F2 and login to terminal, then restart lightdm and for next 30-40 minutes is fine. Sometimes I can't login with ctrl+alt+F2. With Unity 2D is the same. Now testing the system with gnome classic (no efects) and 2 days work without freezes or locks. In the logs I can't see abnormal info. I atach pictures, because, after reboot in the logs cant see theese mesages. uname -a Linux nb5nc6400ub 3.2.0-20-generic #32-Ubuntu SMP Thu Mar 22 02:23:36 UTC 2012 i686 i686 i386 GNU/Linux tolostoi@nb5nc6400ub:~$ lspci 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) 00:01.0 PCI bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express PCI Express Root Port (rev 03) 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 2 (rev 01) 00:1d.0 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7-M Family) SATA Controller [AHCI mode] (rev 01) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI M52 [Mobility Radeon X1300] 02:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 02:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD) 02:06.3 SD Host controller: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller 02:06.4 Communication controller: Texas Instruments PCIxx12 GemCore based SmartCard controller 08:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5753M Gigabit Ethernet PCI Express (rev 21) 10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) tolostoi@nb5nc6400ub:~$ lsb_release -a No LSB modules are available.
