Screen goes black on older laptops after applying August Upd

We are running 11.2.1. Applied the August Imaging Update. Now one of our older model laptops (Latitude D630) gets part way through the boot process and the screen goes black.

I noticed on the new models that the resolution has been increased and I am assuming that is the issue, but Novell support doesn't think so. I have an open SR, but just thought I would post.

Thanks in advance,

Eric

Re: Screen goes black on older laptops after applying August

Hello Eric,

whe have the same problems on Dell Latitude E6410 and on the E6430 we have an flickering screen. I have open an SR too. I have found that the August Imaging Driver Update have changed the Linux Kernel to 3.0. I have test this with Ubuntu Boot CD 11.10 that use the Linux Kernel 3.0 too and i have the same result. When i use the ubuntu boot cd 12.4.1 that have a Linux Kernel 3.2 all it´s fine.

Best Regards

Martin

Re: Screen goes black on older laptops after applying August

Hello Eric,

i have found a workaround for this problem. Edit the config file /srv/tftp/z_auto.cfg and/or z_main.cfg and add to the end by the $KERNEL_PARMS the command nomodeset

Here my config

ZENWORKSAPPEND 1
DEFAULT imaging
LABEL imaging
kernel boot\linux
append 5 initrd=boot\initrd mode=2 rootimage=/root install=tftp://$PXESERVER/boot splash=silent vga=0x314 tftptimeout=50 $KERNEL_PARMS nomodeset


I hope this help you.

Best Regards

Martin

Re: Screen goes black on older laptops after applying August

I've been having this same issue on Compaq 6710b laptops. I created a boot CD and about 50% of the time I can get to the bash prompt, the other half it goes black and I have to force shut down and try again. It seems to happen as udev is starting up.

Re: Screen goes black on older laptops after applying August

This is still an issue for us with the November update, we added nomodeset to PXE Kernel Boot Parameters in ZCC as a workaround

Jdofaz,

yes, the nomodeset stuff is still being worked on, we dont' want to
include it by default until we're sure it doesn't break anything
