Latitude D620 Diplay freeze up when using fc6
govi...@gmail.com
I'm a new member of this group. I have the follwoing problem.
I have a Dell laptop D620 1.66Mhz core duo processor with
945GM chipset for integrated video card. I installed FC6 32 bit on it.
During installation I was not able to use the video display and it kept
going into the text mode. After install I edited my /etc/X11/xorg.conf
file and changed the
"i810" driver to "vesa" and the display seemed to work fine at 1024x768
resolution. It was running fine for couple of days. But all of a sudden
it does not boot and the video display freezes with speckled dots and
arbitrary colors.
I have tried almost everything I could think of and also what people
have suggested on the web but it does not work.
Here are the things I have tried.
1) booting from Linux rescue and changing the inittab to set init3
instead of 5
2) I tried changing "vesa" driver string to i810 but no use.
3) I downloaded 915resolution program from the web and changed the
resolution to "1280x800", "1024x768"
and bunch of other modes. also 8,16 and 24 bits but no use. it appears
that the videocard never works with i810 driver it always says nousable
modes found or some such error message. However it does not freeze the
display. But using the vesa driver freezes the display.
4) I'm beginning to think somehow that the vesa driver must have gotten
corrupted and I need to re-install it but cannot find it. can somebody
please point me how to use
yum and grab the vesa driver for the intel 945GM chipset and I'll give
that a shot too.
5) I managed to get an error message instead of the freeze by hitting
the backspace button twice !!
It still freezes my Display screen and then goes back to the prompt
saying
(WW) VESA(0): failed to set up write-combining
range(0xc0000000,0x7b0000)
(EE) AIGLX: Screen 0 is not DRI capable
and then dumps the backtrace.
does anybody have a clue as to what this might be ?
I installed fglrx driver but I'm not sure it works with intel 945 GM
chipset.
6) i'm relatively new to linux and I have run out of options at this
point- HELP !!! is the only thing I can look forward to .
thank you
