slow boot, 9.5 minutes, of 9.10 upgrade from 9.04

Asked by bobserf

During cold boot or restart of 9.10, white ubuntu logo shows briefly, then screen goes blank for more than 9 minutes (except for a few random ~10 msec flashes) until the word ubuntu appears in white and the desktop loads. Before upgrade, 9.04 booted in ~15-20 secs. Everything else seems o.k. except firefox page scroll, once activated by click, won't stop until page end.

Open Firefox, then type about:config in the address bar and hit Enter.

In the Filter box, type mousewheel.withnokey.

Right-click mousewheel.withnokey.sysnumlines and then click Toggle. This should set the value to False.

Right-click mousewheel.withnokey.numlines and then click Modify. Bump the value to 6 or so, click OK, and then switch to another tab to see if you like the scroll speed.

I tried what wojox suggested and what Nigel Babu described in response to Bug Report #483338, and observed no improvement. Then I changed the frame buffer size in BIOS from 32kB to automatic, and both the boot delay and scroll problems were solved. I believe that 9.10 updated the ATI Radeon driver in my system without notifying me. ATI Radeon integrated graphics users upgrading from 9.04 to 9.10 might wish to try changing the frame buffer size in BIOS. Thank you for your suggestions. I learned more about my system through this interaction, and I hope my suggestion helps somebody.

Can you help with this problem?
