Version: (using KDE 3.5.10) Compiler: gcc-4.3.2 OS: Linux Installed from: Gentoo Packages kdm starts correctly always. The problem comes when I log out, kdm crashes and I have to log in the text console and restart the kdm service. My video card is a sis, this is the lspci output: 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 661/741/760PCI/AGP or 662/761Gx PCIE VGA Display Adapter And this is the message I get in /var/log/xdm.log (In gentoo this is the login manager logfile): xdm error (pid 2791): Display :0 is being disabled (EE) SIS(0): Unable to map IO aperture. Invalid argument (22) (EE) SIS(0): ************************************************** (EE) SIS(0): ERROR: (EE) SIS(0): Could not map MMIO area (EE) SIS(0): END OF MESSAGE (EE) SIS(0): ************************************************** (EE) SIS(0): ************************************************** (EE) SIS(0): ERROR: (EE) SIS(0): SiSMapMem() failed (EE) SIS(0): END OF MESSAGE (EE) SIS(0): ************************************************** Fatal server error: AddScreen/ScreenInit failed for driver 0
that's a driver problem and kde cannot do anything about it. you might try the TerminateServer option in kdmrc to work around it.
