Something wrong with the shutdown [Solved]

[apiaio]

Hi there.
Today I upgraded system and kernel as well. Now I have

sabayon # uname -r
3.6.0-sabayon

Everything seems to be OK. When I want to reboot from KDE or I switch using ctrl+alt 1,2 etc. the screen becomes black and at the bottom are green- blue lines and PC freezes.
Has anybody similar problem?

EDIT:
It will be something wrog with KDE, because problem occures after kdm starts.

I started SL with old kernel version 3.1.0-sabayon and everything is OK. I rebooted again into version 3.6.0-sabayon and find out, that the problem started after message

Code: Select all

starting framebuffers console settings -----

EDIT:
The resolutioun during startup of the kernels is different.

Perhaps it's a bug in SL, so I suggest you file a bug report (To do that click on the link 'Bugs' at the top of this page).

What videocard/driver are you using?
Did you catch the message on the notice board about kernel 3.6?

Important AMD GPU related changes in Linux Kernel 3.6+
Sun, 14 Oct 2012 20:12:39 +0000, sabayonlinux.org

Kernel updates are not forced to users. If you do not intend to update your kernel or you don't even know what a kernel is, you can happily ignore this notice. However, if you are adventurous and want to update your kernel to 3.6 (or later) and you have an AMD graphics card using the proprietary drivers (ati-drivers), you must add "nomodeset" to the boot parameters, or 3D acceleration will stop working. This is because upstream X.Org OpenSource Radeon drivers are not supporting non-KMS configurations anymore. So yes, OpenSource AMD graphics drivers will work 100% out of the box now.

Thanks for answers. Probably both of you are right. I downgraded into

Code: Select all

sabayon / # uname -r
3.5.0-sabayon


and everything works.
Thanks

Well...i'm unable to add nomodeset to boot parameters.

How to do that safely?

(Im still learning, thanks.

** This is ONLY needed for kernels > 3.6 combined with the fglrx drivers. **

/etc/default/grub and add nomodeset to the GRUB_CMDLINE_LINUX_DEFAULT variable

Regenerate your grub.cfg file:

Code: Select all

grub-mkconfig -o /boot/grub/grub.cfg

Reboot.

Thank you joost, I understand.

Another question: can I add nomodeset using kernel 3.5.7 (i'm using this one, instead off I installed 3.6.1), or I must relog and use kernel 3.6?
Thank you.

(what nomodeset do?)

[joost]

The OpenSource ati driver needs this. It triggers KMS (Kernel Mode Setting), this allows to early set the monitor resolution.
We used to have this OPTIONAL as a kernel Module in Kernels < 3.6 but since 3.6 we have this build in the kernel, and it is enabled by default. Sadly this conflicts with the FGLRX driver.

http://en.wikipedia.org/wiki/Kernel_mode-setting
https://wiki.archlinux.org/index.php/Ke ... de_Setting

With Kernel Mode Setting (KMS), the kernel is now able to set the mode of the video card. This makes fancy graphics during bootup, virtual console and X fast switching possible, among other things.

can I add nomodeset using kernel 3.5.7

Sure, if you don't use the FOSS ati driver, it does no harm.

3d accelerations seem working fine, but i still can't shud down the system:
when shutting down, i can see a persistent black screen with a blue line on the bottom
