Binary package hint: xserver-xorg-video-ati
I am currently testing Kubuntu 10.04 alpha3, and everything works OK except that:
- there is no splash screen and no boot messages on startup (the screen goes blank after making a selection in GRUB and does not turn on again until the graphical KDM screen appears) and
- ** the tty consoles do not work ** (Ctrl-Alt-F1 and the like). There is no adequate response to the Ctrl-Alt-F1 (...F6) keys, i.e. the KDE desktop stays on the screen, the mouse cursor disappears, but nothing further happens. The /sbin/getty processes are running for tty1 to tty6. sudo chvt [1-6] has the same effect. Initially, on Ctrl-Alt-F8 the mouse cursor used to reappear (i.e. switching back to the GUI worked). After the latest updates, trying to switch to a virtual terminal seems to freeze the GUI and, since there is no accessible terminal and a frozen GUI, requires a reboot.
I suspect that the problem has something to do with the framebuffer.
System information: OS: Ubuntu lucid (dev) · Kernel: 2.6.32-16-generic · KDE: 4.4.1 (KDE 4.4.1)
CPU: AMD Turion(tm) Dual-Core Mobile ZM-82 · RAM: 1367392kB/3799764kB

Installed graphics driver: automatically with OS installation, no modification. Loaded module is radeon.
latest updates as of March 17, 21:20 UTC using default sources.list(.d/*) from 10.04 alpha3
What I already did:
1. create a minimal xorg.conf and place Option "DontVTSwitch" "false" in it (does not help)
2. uninstall plymouth (does not help)
3. place radeon.modeset=0 in kernel grub line (and remove quiet splash). This makes the boot messages appear and restores the normal function of the virtual terminals. This is a workaround, but: slow graphics, no acceleration, no effects.
The problem does not depend on the desktop/window manager, it appears in KDE/KWin and whatever Gnome uses (compiz or metacity) alike. As a side note, I am using two screens (laptop LVDS and external VGA-0/VGA-1) with xrandr.
