GRUB update problems

[Henry W. Peters]

I run Debian Lenny sid/squeeze, the updater this morning just "updated" 
my GRUB2 version... (not sure of the version).

Anyway, I have a Dell S1909 WX monitor at resolution 1440 x 900 
(analogue) at 60 Hz. (the recommended resolution). I do dual boot with 
Windows XP (sp3) & besides a GNOME desktop, I have xfce installed. So I 
use GRUB bootloader.

Since I got this monitor (I previously used Ubuntu distro), I have had a 
problem with it & Linux... (i.e., not in Windows). I discovered that I 
needed to change the display resolution via the 'Startup-Manager.' This 
apparently changes the resolution in GRUB. With the last two versions of 
GRUB, this worked fairly well, the  vertical lines (like a double 
shifted image) almost completely disappeared. This "newest" version of 
GRUB, the lines are back full force, & no parameter that I set in the 
'Startup-Manager' helps... (though, as a side note...  when set to so 
work with working monitor res. the text in the startup routine was too 
tiny for words (to be read)). It appears to be two display drivers 
conflicting... (????)

I probably need to get the display resolution in GRUB to correspond to 
my ACTUAL desktop resolution... I'm guessing; so, until GRUB  works out 
what appears to me, to be a 'bug' (?), or I can know what to do to 
remedy... perhaps there is a workaround someone can suggest?

& one more note, I also had a problem with GRUB (or what ever...) when I 
hit the restart/shut down routine... it would sometimes only do a log 
off, & then I would have to do a restart from the log on screen, well... 
it's back with this recent version of GRUB.

Any helpful help appreciated.
