entire Xorg.0.log

I just upgraded to the intel driver in version 2.99.905 in order to try the
improved TearFree option. It seems to work fine (yay, thanks!), but a couple
minutes later my display just turned off. Switching to vt1 and back to vt7 was
enough to get it back on, but I suspect this will happen more often, so I
figured I’d report it.

The last few lines in /var/log/Xorg.0.log are:

[2450513.409] (II) intel(0): switch to mode 2560x1440 at 60.0 on pipe 0 using DP2,
position (0, 0), rotation normal
[2451327.200] (EE) intel(0): sna_mode_redisplay: page flipping failed,
disabling CRTC:3 (pipe=0)
[2451340.647] (II) AIGLX: Suspending AIGLX clients for VT switch
[2451346.532] (II) Open ACPI successful (/var/run/acpid.socket)
[2451346.532] (II) AIGLX: Resuming AIGLX clients after VT switch
[2451346.532] (II) intel(0): switch to mode 2560x1440 at 60.0 on pipe 0 using DP2,
position (0, 0), rotation normal

Full Xorg.0.log attached. Please let me know if you need any other information.
