I'd expect it to report CRTCs 0 and 1, as both of them can drive the output when it is connected (and this is what it did before, IIRC) 3) xscreensaver fails. If at this point one runs xrandr --addmode VGA-0 640x480, the server crashes with Backtrace: 0: /usr/bin/X(xorg_backtrace+0x26) [0x4ebd56] 1: /usr/bin/X(xf86SigHandler+0x39) [0x47f949] 2: /lib/libc.so.6 [0x7f637896ef80] 3: /usr/lib/xorg/modules/drivers//nouveau_drv.so [0x7f63773c2fe6] 4: /usr/bin/X [0x4adfbb] 5: /usr/bin/X(RROutputAddUserMode+0xa4) [0x525d64] 6: /usr/bin/X(Dispatch+0x364) [0x44c2d4] 7: /usr/bin/X(main+0x45d) [0x432bcd] 8: /lib/libc.so.6(__libc_start_main+0xe6) [0x7f637895b1a6] 9: /usr/bin/X(FontFileCompleteXLFD+0x269) [0x431fa9] Fatal server error: Caught signal 11. Server aborting inside nv_output_mode_valid (I think nv_encoder is NULL at this point). When a display is connected to VGA-0, xrandr reports CRTCs: 0 1 for VGA-0, and everything works as it should (xscreensaver included). If the display is disconnected, everything keeps working (and xrandr --addmode no longer crashes the server), the CRTCs: 0 1 line remains in the VGA-0 output of xrandr. So, I don't know for sure if it is wrong to report no CRTCs for a disconnected output, but the fact that the reported CRTCs change after an external display is plugged and unplugged again, and the related crash of the Xserver seems to imply that there is a bug with this. I've changed the description accordingly. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
