I can exit X and restart X successfully. I can also switch (ctrl-alt-F1-F8) between X and console and back (ctrl-alt-F9). Even with glxgears running. No lock-up. It is an AGP card: (--) RADEON(0): Chipset: "ATI Radeon 9600XT AR (AGP)" (ChipID = 0x4152) (--) RADEON(0): Mapped VideoRAM: 131072 kByte (128 bit DDR SDRAM) These are my modules: Section "Module" Load "extmod" Load "record" Load "dbe" Load "glx" Load "dri" Load "dri2" EndSection And nothing special in the driver section.
