[Bug 129910] Re: Blank ttys when using vesafb (vga=xxx)

[Fabio Marzocca]

You're right, Loye, I should have provided more informations.

Here they are:

1. nvidia-glx   1:1.0.9639+2.6.22.4-14.10

2. fabio at Plato:~ $ lsmod | grep fb
vga16fb                15500  0 
vgastate               11008  1 vga16fb
vesafb                  9092  1 
fbcon                  41760  72 
tileblit                3584  1 fbcon
font                    9344  1 fbcon
bitblit                 6912  1 fbcon

3. fabio at Plato:~ $ lsmod | grep agp
agpgart                35016  1 nvidia

4. I switch to tty-1 with Ctrl-Alt-1. Only on that tty I see the line "Loading. Please wait...". On other tty's there is a blank screen
    If I go to single-mode user (with telinit 1) the tty screen is good.

5. kernel               /boot/vmlinuz-2.6.22-14-generic
root=UUID=ead6c453-7721-49c0-ad26-1287c8486460 ro quiet splash vga=791
quiet splash

6. /etc/modules: 
psmouse
mousedev
lp

/etc/initramfs-tools/modules
fbcon
vesafb
vga16fb

7. Relevant log messages:

8. I blacklisted vesafb and vga16fb

Thank you.
