On Lenovo-T60 with Ati Mobility Radeon (radeon-driver) I get a flickering display when in init 3. The screen goes blank every 10 seconds for some milliseconds and comes back. This does not happen when in KDE/init 5 and was not with kernel 3.1-0.slh.2.
      Code:
infobash -v3
Host/Kernel/OS  "T60" running Linux 3.1-0.slh.3-aptosid-686 i686 [ aptosid 2010-03 Ἀπάτη - kde-lite - (201012262151) ]
CPU Info        2x Intel Core2 T5600 @ 2048 KB cache flags( sse3 ht nx lm vmx ) clocked at [ 1833.000 MHz ]
Videocard       ATI M52 [Mobility Radeon X1300]     [  ]
Network cards   Intel 82573L Gigabit
                Intel PRO/Wireless 3945ABG [Golan]
Processes 161 | Uptime 12min | Memory 609.6/2025.2MB | HDD SAMSUNG HM321HI Size 320GB (22%used) | Client Shell | Infobash v3.37

Please tell me what more hardwareinfo/logs/messages/outputs etc you need to hunt this down.

Please look for anything revealing in dmesg and/or /var/log/Xorg.0.log. Personally I can't reproduce that issue on rv360 or rv630, which makes it a little hard to bisect.

I compared dmesg and other logs between the .2 and .3 Kernel, looking for differences or errors regarding vga/video/radeon/framebuffer and such. Nothing obvious. No interesting entrys in Xorg.0.log as this happens when directly booting from grub into init 3, but not in X. Will stay with last kernel for a while and see what happens with the next ones.

I've got the same problem with my T60 and Ati Mobility Radeon X1400!
Additionaly: The problem occurs on an external display connected to VGA, too, even in X, but only on the second monitor.

As der_bud I can't find anything in dmesg or other logs. Any hint where to look for errors?

Info: it's not gone with Kernel .slh.5 Sad
What tools other than top/htop can observe what "happens in the system"? Perhaps I could see what flashes every 10 seconds. And for me still not in X, but init 3 or Strg+Alt+F1, so some Framebuffer-Thing?

On my Thinkpad X60, it doesn't flash. What grafic card you have? KMS enabled? for intel grafic cards RC6 enabled?

Hi hefee, graphics is Ati Mobility Radeon X1300, kms enabled, xserver-xorg-video-radeon. Played around with nomodeset and several acpi/apic on/off combinations in grub, but no changes.

Hi

I need some feedback to debug this issue further, as I unfortunately can't reproduce it locally. Please test each (well, only the ones for your architecture, of course) of these kernels individually and report which kernels are working and which expose your KMS/ tty flickering. Furthermore I'd need the output of the files/ commands below for a working (3.1-*) and a non-working (3.1-*) kernel[1]:
- dmesg
- lspci -nnvvvvv (only once, this doesn't change between kernel versions)
- /var/log/Xorg.0.log

3.1-5.1:
amd64: linux-image-3.1-0.slh.5.1-aptosid-amd64_3.1-5.1_amd64.deb
i386: linux-image-3.1-0.slh.5.1-aptosid-686_3.1-5.1_i386.deb

3.1-5.2:
amd64: linux-image-3.1-0.slh.5.2-aptosid-amd64_3.1-5.2_amd64.deb
i386: linux-image-3.1-0.slh.5.2-aptosid-686_3.1-5.2_i386.deb

3.1-5.3:
amd64: linux-image-3.1-0.slh.5.3-aptosid-amd64_3.1-5.3_amd64.deb
i386: linux-image-3.1-0.slh.5.3-aptosid-686_3.1-5.3_i386.deb

you can install these via "dpkg -i linux-image-3.1-0.slh.5.*-aptosid-686_3.1-5.*.deb" after downloading and switch between them in your grub2 menu.

[1] Feel free to send those logs via forum PM, if you're not comfortable to attach them here.

Short Notice: -5.2 and -5.3 are working, -5.1 is not. I will post the required info and pastes later today.

-----
edit: here the logfiles on paste.debian.net

to lspci -nnvvvvv : http://paste.debian.net/143567/

Kernel with display flicker is 3.1-0.slh.5.1
to Xorg-log Kernel -5.1 : http://paste.debian.net/143572/
to dmesg Kernel -5.1 : http://paste.debian.net/143569/

Working kernel is 3.1-0.slh.5.3
to Xorg-log Kernel -5.3 : http://paste.debian.net/143577/
to dmesg Kernel -5.3 : http://paste.debian.net/143575/

Greetings, der_bud

To be sure, please test 3.1-5.4 as well.

3.1-5.4:
amd64: linux-image-3.1-0.slh.5.4-aptosid-amd64_3.1-5.4_amd64.deb
i386: linux-image-3.1-0.slh.5.4-aptosid-686_3.1-5.4_i386.deb

I don't need any logs from this one, just [works|does not work], ideally also from dkadioglu's X1400 mobile.

Hi slh,

thanks for debugging this! With linux-image-3.1-0.slh.5.4-aptosid-686_3.1-5.4_i386.deb
the screen is not flickering anymore (not in init 3 and not on external display)!

Regards
dkadioglu

We have a, hopefully, final patch from the maintainer, which needs testing:

3.1-5.5:
amd64: linux-image-3.1-0.slh.5.5-aptosid-amd64_3.1-5.5_amd64.deb
i386: linux-image-3.1-0.slh.5.5-aptosid-686_3.1-5.5_i386.deb

Yep. The last one is working, too. Thank you very much for that.
