With an Asus ENGT430 card, which the box says is a GeForce GT 430,
and with 64-bit Mageia 1 with kernel 22.214.171.124-server-10.mga, about
once a week, the mouse cursor disappears from at least one monitor
or the display locks up when exiting X. (I use runlevel 3 and
startx.) Usually, if the cursor disappears and I then exit X, the
display will lock up showing the X root window background. Once
the display has locked up, Alt-Ctrl-F* does nothing, SysRq does not
display anything (so I can't tell what it's doing). However, I'm
able to ssh into the system, and everything other than the display
is fine. After a reboot, everything seems fine. I don't think I
saw this problem until I did a sensors-detect and added a second
monitor. (Main monitor is on DVI, and second monitor is on HDMI.)
If I gather correctly, he GeForce GT 430 is an NVC1, GF108.
Is there any known way to recover from an invisible mouse cursor
or locked-up display other than rebooting? I understand there is
functionality in the kernel to manually switch between virtual
consoles. Can that be used to force the card to complete the
transition from X to a text console?
