Half a Page of Scribbled Linux

Resuming from hibernation in Ubuntu 10.04 shows a blank screen, then a corrupted video image for a second or two before showing the log in screen.
Changing the video resolution with Startup-Manager from 640×480 and 8 bits to 1024×768 and 24 bits replaced the blank screen with the Ubuntu Plymouth graphic and the message “resuming from “. There’s still the brief corrupted video before the log in screen, but at least there’s not a blank screen for half a minute. BTW, that corrupted video image has been there since Ubuntu 8. The video is an Intel 945GM Chipset.

When booting or resuming a hibernated session in Ubuntu 10.04, my screen is blank with the exception of a couple lines of text:
Boot from (hd0,2)[…]
Starting up...

I was looking to get a graphical screen back that I had in Ubuntu 9.10.

I found some tips at Ubuntu Geek.

For me the relevant stuff was this:
sudo -s
echo FRAMEBUFFER=y >>/etc/initramfs-tools/conf.d/splash
update-initramfs -u

I had my Thinkpad T60 set up to hibernate at the log in screen when the lid is closed. After updating Ubuntu to 10.04, this didn’t work any more. I’ve gotten used to upgrades resetting this behavior, but this time the steps I’ve used in the past didn’t work.

With a little Googling, I came up with these modified instructions:

• Log out of your X session
• Go to a TTY session with Ctrl+Alt+F1
• Log in
• export DISPLAY=:0
• sudo -u gdm gconf-editor
• Switch to the graphical session with Ctrl+Alt+F8 (note, the graphical session used to be F7, but in Ubuntu 10, it’s now F8. If F8 doesn’t work try F7 or F9.
• Select /apps/gnome-power-manager/buttons/lid_battery and change the value to hibernate
• Close gconf-editor
• Switch back to the TTY session and log out
• Go back to the log in session with Ctrl+Alt+F8

Ubuntu has not been adding kernels in /boot/grub/menu.lst since about version 8. Running sudo update-grub hangs. Thinking it must not like my older menu.lst, I did this:

I got this prompt:
Could not find /boot/grub/menu.lst file. Would you like /boot/grub/menu.lst generated for you? (y/N)
I answered yes and it made a version update-grub could live with. All I had to do is go back and add the menu options for my dual boot partitions.

I upgraded Pinto, a Thinkpad T60 from Ubuntu 9.10 to 10.04 SLT. The upgrade went almost without a hitch.

The first issue was on the reboot. I can’t blame this on the upgrade, though. Since at least Ubuntu 8, /boot/grub/menu.lst doesn’t get updated whenever a new kernel is installed. So on reboot, I got the kernel version Ubuntu 9.10 was using. Manually editing menu.lst fixed that.

After a reboot, the first thing I noticed was middle mouse button scrolling didn’t work. Googling “ubuntu 10.04 middle button scroll” turned up a fix.
