I am using Xubuntu alpha 2 amd64 10.04 on radeonhd 4670 () with old CRT monitor Hitachi cm772.
I have to uninstall plymouth (graphical boot animation and logger - main package) to get rid of pc lock up on enter push. And i use nomodeset on boot kernel options to get rid of screen luck up on changing rezolution from 1600x1200 85hz to 1024x786 85hz. I think problem is in 85hz. If i choose not 85hz then screen don't luck up. The system is not lock up in this moment, because i can switch terminal (console) by pressing Ctrl+Alt+F1 and login. The PC is not laptop, but still the problem similar ;) technical data: uname -na Linux xxxxxx 2.6.32-13-generic #18-Ubuntu SMP Wed Feb 10 21:32:38 UTC 2010 x86_64 GNU/Linux lspci 00:00.0 Host bridge: Intel Corporation 4 Series Chipset DRAM Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation 4 Series Chipset PCI Express Root Port (rev 03) 00:1a.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #4 00:1a.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #5 00:1a.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #6 00:1a.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #2 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller 00:1c.0 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Root Port 1 00:1c.5 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Root Port 6 00:1d.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #1 00:1d.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #2 00:1d.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #3 00:1d.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #1 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 90) 00:1f.0 ISA bridge: Intel Corporation 82801JIB (ICH10) LPC Interface Controller 00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI Controller 00:1f.3 SMBus: Intel Corporation 82801JI (ICH10 Family) SMBus Controller 01:00.0 VGA compatible controller: ATI Technologies Inc RV730XT [Radeon HD 4670] 01:00.1 Audio device: ATI Technologies Inc RV710/730 02:00.0 Ethernet controller: Attansic Technology Corp.
