On Ubuntu 9.10 Karmic.
Sometimes, when I try to login, the login box disappears and the usplash
(I think) starts as usual (with the scrolling bar). Within two or three
seconds, the screen goes black, I get some errors, then the login screen
again. I often have to make two or three attempts to finally get a
successful login.
Conditions: The default screen resolution is 1152 x 864; 75Hz. Because
of a very awkward and rare problem, my CRT monitor sometimes starts
squeaking a very high pitch. I discovered that by changing the refresh
rate (to anything else), the squeaking stops. (e.g my screen starts
squeaking when the refresh rate is 75Hz, I change it to 60Hz and it
stops, or vice-versa). So if I change the refresh rate to 60Hz (when the
screen squeaks at 75Hz), my refresh rate and the login screen refresh
rate is different. If this is the case (my refresh rate[60Hz] not equal
to login screen refresh rate[75Hz]) then I am often unable to login. The
screen flashes black (like it is supposed to when changing the
resolution), and then a black error screen is seen. After this usplash
continues, except not to log me in, but to go to gdm).
This is a fresh install of Ubuntu 9.10 Karmic Koala. I do not know
whether I have a graphics card (I seriously doubt it, because I am
unable to use Desktop Effects). I am willing to submit any other data
that is required.
Reproducible: Not always. Since I am able to login after a couple of
attempts. Even when the screen resolutions are not equal, I rarely am
able to login in my first attempt.
Other info:
- I have not been able to note the error messages down as yet.
- Yes, I am sure I typed in my password correctly. If I don't, I am not allowed
to get to the point where usplash starts scrolling a bar on the screen.
- This happens after around the bar completes one full scroll, sometimes two.
FYI, for the whole login process, Ubuntu consistently takes 14 or 15 scrolls or
scrolling cycles (whatever you call it).
- I have never tried it with a different screen resolution (e.g 1024*768)
I consider this a serious bug.
