No video after 2.6.6 kernel upgrade

WopMaster8 · 05-25-2004, 01:04 AM

I'm running a Dell Inspiron 5100 with Slackware 9.1. After upgrading from kernel 2.4.22 to 2.6.6 I get no video at all on boot. It appears the system is booting okay otherwise, judging from the LED activity. I made sure to leave the old kernel intact in lilo just in case and that one still boots fine. I probably missed something during the "make menuconfig" stage, so does anyone have any experience with this system and OS? Also, any additional tips would be helpful. Here are the steps I took to upgrade the kernel after the untar to /usr/src:

ln -s /usr/src/linux-2.6.6 /usr/src/linux

cd /usr/scr/linux

make menuconfig

make bzImage

cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.6.6

rm /boot/vmlinuz

ln -s /boot/vmlinuz-2.6.6 /boot/vmlinuz

make modules

make modules_install

cp System.map /boot/System.map-2.6.6

cp .config /boot/config-2.6.6

ln -s /boot/System.map-2.6.6 /boot/System.map

ln -s /boot/config-2.6.6 /boot/config

I then edited the /etc/lilo.conf file to boot the new kernel (or the old one, thankfully) and ran /sbin/lilo.

run the x configurator to setup your mobility radeon ..
here is a sample XF86Config file ..

and i know this next link is gentoo based, but you'll have the right idea to get
done what has to be done...

Try passing vga=normal to the kernel at the bootloader prompt (using the E key to edit the kernel line in Grub, or just append it if you use Lilo). It should boot showing the regular messages.

Check your bootloader configuration and verify that the video mode selected in the bootloader's configuration is supported in the kernel. You might for instance want to have video textmode selection support and framebuffer console support enabled in your kernel to get a working high-resolution console.
