If I press Ctrl-Alt-F1 when the boot completes (i.e., when the disk access stops), the text console screen appears and shows a login prompt as expected (in the PC's native resolution). And after I see teh text console, I can press Ctrl-Alt-F7 to show the graphical login screen, but on the display the *lower half* of the graphical login screen appears on the upper half of the physical display, and the lower half of the dispay is just black. The Ctrl-Alt-F7 works only after seeing the text console; if I pressed Ctrl-Alt-F7 immediately after the boot completion (without pressing Ctrl-Alt-F1), nothing happens on the display. When I typed a user ID and password on the half-trimmed graphical screen, I can login to the graphical desktop, but the lower half of the display is still black, and the upper half of the dispay appears showing *both* upper and lower halves of the logical screen, overwriting each other in parts in a redraw order. And if I can manage to logout, the display shows the login screen correctly (after a gray transition screen). The above behaviour is observed when booting from a system installed to the disk drive using the Live CD. Booting the Live CD itself does not cause the black out; it causes upper-half phenomenon only. The graphical boot screen first shows up using entire display. It is later broken with several kernel error messages, but the slowly brinking dots under the ubuntu logo are visible during the entire boot process. After completion of the boot, some broken graphical screen (intended for asking "Try ubuntu" or "Insall") appears on the upper half of the display, leaving some kernel error messages on the lower half of the display. If I can manage to choose "Try ubuntu" on the broken screen, the tryout desktop appears correctly using entire display. (So, I could install ubuntu to the disk drive.) If I entirely disable plymouth on the installed system (i.e., remove all /etc/init/plymouth*.conf files as suggested in pages found by google search), the blackout-during-and-after-boot behaviour persists, but the first graphical screen I see after boot, then Ctrl-Alt-F1 then Ctrl-Alt-F7 appears correctly using entire display, so I don't need an extra login-logout cycle on a broken screen. That's my current workaround... I'm using Fujitsu Lifebook TH40D, a "hybrid of note and tablet" PC. It has Atom Z670 with SM35 Express chipset, providing GMA 600 graphics subsystem. I trid Live CD media of 12.04 LTS (Precise angolin) alpha 1. The installed system's behaviour persists after "apt-get dist-upgrade" today (2012-01-22 Japan time). P.S., I'm exciting to see the poulsbo support in ubuntu comes to very close to production use, and is very likely to be integrated in the official ubuntu distribution soon. I appreciate GMA500 team. Hope this report help improving the psb_gfx driver.
