Running AMD965 / MSI_790fx_gd70/ gtx 9800+ on fully patched Ubuntu 10.04.LTS including latest post-April 13 kernel update.
In the last two weeks my monitor on-boot has begun (random?) **flashing** on/off to a black screen **after** an initial stable mobo screen display. So the sequence-of-appearance is:
1) stable mobo flash-screen
2) alternate boot-display/black_screen for ~ 30 seconds
3) stable display thereafter: NV_280.13 driver @ 1920x1200 & vidcard running legacy value of 60-C
Very disconcerting considering Hanns-G 28" bad reputation for early death ( mine has been perfect for 3.5 years ).
Though never looking before, I checked X-ORG log and observe an apparent display "checking" anomaly for screen resolution: I have not copied the entire log --- just near the end --- but similar entries for all screen resolutions appear at earlier stages.

Note that X.org finally settles on the proper 1930x1200 resolution. I'm way over my head in this issue gents. Is my Hanns-G monitor about to give-up-the-ghost or is something in the boot-sequence flummuzing the display? Any comments appreciated.
