Description of problem:
I upgraded to kernel-2.6.9-1.724_FC3 and when the systems boots up it
does not load vesafb.(default console..)
After upgrading to kernel-2.6.10-1.727_FC3 (gdb bug....) the problem
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot with any vga=xxx paramenter
2.notice that there is no vesafb
Actual Results: no vesafb
Expected Results: vesafb should be loaded
which value are you using for xxx ? Here vga=791 works just fine.
I use vga=794. I tested it with 791 and it works. 794 (1280x1024)
worked well with kernel-2.6.9-1.681 now I am using 2.6.10-1.737_FC3.
I will attatch the output of dmesg and lspci.
Created attachment 109623 [details]
Created attachment 109624 [details]
output of lspci
but no one seems to work...
why deos vesafb no longer works at 1280x1024?
My problem is complete garbage on the screen at bootup,
the only way around it is to use vga=ask and then choose
number 0 ; any other combination of vga=xxxxx does not
fix the garbage. Even after boot, the login prompt screen
has crap on it. What do I do to fix this?
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
I updated to fc4 and still has the same problem.
Mass update to all FC4 bugs:
An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (18.104.22.168). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.
This bug has been mass-closed along with other bugs that have been in NEEDINFO
state for several months.
Due to the large volume of inactive bugs in bugzilla, this is the only method we
have of cleaning out stale bug reports where the reporter has disappeared.
If you can reproduce this bug after installing all the current updates, please
reopen this bug.
If you are not the reporter, you can add a comment requesting it be reopened,
and someone will get to it asap.
vga=794 still does nothing... but on my lcd screen+6600GT 791 gives me 1280x1024
I'm puzzled why 794 doesn't work for you. I suggest taking this up with the
upstream maintainer of the frame buffer layer, Antonino Daplas <firstname.lastname@example.org>
as he may have some ideas. If he comes up with some fix, Fedora will pick it up
as soon as it's in Linus' kernel.
