LCD screen is blank after lilo on VGN-S580P

dasoberdick · 06-15-2007, 03:13 PM

I am having module issues so I figure if I was going to have to recompile the kernel I might as well just compile a new one.

So I configured and compiled the 2.6.21.5 kernel. Added the new image to Lilo and rebooted. The dots scroll across the screen and then its blank, i got nothing. But I can still hear the hard drive ticking and the read light is on. control alt delete and the thing reboots so i figure i just have display issues. I changed an LCD option in the kernel (something like add LCD and backlight support, thought that might help even though i have no clue what it does), reboot and nothing. But I let it go anyways and just on a whim, after I had already started typing this message, I decided to try to log in anyways. I log in, type startx and bam the X server comes up and I have a display.

What is going on?

Did you remember to run '/sbin/lilo' after changing '/etc/lilo.conf' ?

I am also having some odd problems with my LCD during boot, but in Debian. From time to time, the screen will act like it is going bad. IOW, anything that is displayed will fade out from the center to the edges. If I CTL-ALT-F1 and then CTL-ALT-Del to reboot, it will come up just fine. I have no idea what is going wrong. It only happens occasionally and only on bootup. When this problem occurs, I do not get the boot messages on the screen. The first thing I see is the NVIDIA logo flash then it fades away.

yes. I am running the new kernel. I have a working system (minus the freaking wireless which is why I undertook this endevour)

Did you remember to compile in framebuffer support ? (vesafb)

dasoberdick · 06-15-2007, 04:30 PM

nope, what would that be under?

H_TeXMeX_H · 06-15-2007, 05:02 PM

Device Drivers -> Graphics Support -> Support for frame buffer devices

and possibly also

VESA VGA graphics support
(recommended)

dasoberdick · 06-15-2007, 07:28 PM

yeah i did that and I still got nothing.

i have never looked in that file. I always just used the configure program. I guess I'll have to dig into it and take another step up the Linux learning curve.

Well, technically you should not edit it manually, because it involves many dependencies. Some modules require that others be build too. But, when changing one or two minor things, it may not matter. A better way is if you use 'make menuconfig' press the '/' key to search for stuff.
