Well, I already pasted the radeon-kms.conf. I had no xorg.conf for the
initial tests, but I do have an xorg.conf now, because I've been
configuring the synaptics input device and a created an xorg.conf for that.
I could try moving it away and checking if it works or fails. Will get
back about this.

No, the kernel is the same.

Re-installing that machine is not really possible. But it's a really
nice model, and I think I might be getting hold of another one soon.

Well, actually that wasn't what I meant, but it's good to clarify that
in any case. :)

No, this confirms that both KMS and UMS (can) work fine, thanks.

Can't think offhand of anything that could be other
than /etc/modprobe.d/radeon-kms.conf or /etc/X11/xorg.conf{,.d/*} ...
Could it be that it was a different kernel exhibiting the problems?
If not, I'm afraid I don't have any good ideas offhand how to figure out
what happened short of installing again and if the problem still occurs,
saving all even remotely relevant configuration and log files and then
looking for differences in them after the problem is fixed.

I tested it and this was right, after reverting everything back to squeeze, suspend/hibernate work fine. Now I feel like I'm going crazy. It looks like installing ubuntu's packages left something behind that made it work, because with a 100% squeeze system it works fine, when it didn't work 3 days ago, before installing maverick's packages. > KMS should be enabled by default in both cases, so colour me skeptical. > But you can try flipping it with the radeon kernel module parameter > 'modeset' to see if it makes any difference in either case. It was set to 1. I tried setting it to 0, and something new happened: both suspend and hibernate worked but when it came back it didn't show X, it showed some kernel messages, but doing Ctrl-Alt-F7 worked. I couldn't go back to those kernel messages afterwards. Should I try setting it to something else? > Otherwise, apart from any possible code differences between the driver > package versions (haven't checked yet), I assume that switching between > them also requires switching versions of other packages, in particular > xserver-xorg-core.

This was the state before downgrading back to squeeze: -*- libxfont1 1:1.4.3-1 newer than version in archive wireless-crda 1.12 installed: No available version in archive xserver-common 2:1.9.2.902-1 newer than version in archive xserver-xorg/squeeze upgradeable from 1:7.5+6ubuntu3 to 1:7.5+8 xserver-xorg-core 2:1.9.2.902-1 newer than version in archive xserver-xorg-input-all 1:7.6~2 newer than version in archive xserver-xorg-input-evdev 1:2.5.99.901-1 newer than version in archive xserver-xorg-input-synaptics 1.3.0-1 newer than version in archive xserver-xorg-video-fbdev 1:0.4.2-3 newer than version in archive xserver-xorg-video-radeon/squeeze upgradeable from 1:6.13.1-1ubuntu5 to 1:6.13.1-2+squeeze1 xserver-xorg-video-vesa 1:2.3.0-4 newer than version in archive -*- Some of this packages were from experimental and some from maverick.

What changes are you referring to specifically? I can only see the
changes below, which shouldn't be relevant to your problem.

The Ubuntu version of the driver package depends on the virtual package
xorg-video-abi-8.0, which is not provided by xserver-xorg-core in
squeeze.

Only switching back and forth between kernels. I never tried downgrading the X driver back to squeeze's. I could try that, my guess is that it's a code change and so it won't work, but I'll try it just to document it. > > After looking at the changelogs and differences between the two packages, I > > have the sensation that the problem might be related to kms, but I really > > don't know enough about X to debug this myself. > > KMS should be enabled by default in both cases, so colour me skeptical. > But you can try flipping it with the radeon kernel module parameter > 'modeset' to see if it makes any difference in either case. > > Otherwise, apart from any possible code differences between the driver > package versions (haven't checked yet), I was refering to code differences regarding kms.

Not -core. I did install xserver-xorg from maverick, although I'm not sure if it ships any interesting files. The machine is not mine and I'll have limited access to it after today, which was why I tried to get help debugging this on IRC as quickly as possible, but unfortunately couldn't get it. Anyway, I'll do as much testing as I can before having to give it up, and then my response time about this bug is going to be much slower. -- Love, Marga -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".

Let me get this straight: With the Debian driver package installed, suspend/hibernation doesn't work no matter which kernel etc. you're using. With the Ubuntu driver package installed, both work. And these symptoms remain the same after switching back and forth between the versions of the driver package.

KMS should be enabled by default in both cases, so colour me skeptical. But you can try flipping it with the radeon kernel module parameter 'modeset' to see if it makes any difference in either case. Otherwise, apart from any possible code differences between the driver package versions (haven't checked yet), I assume that switching between them also requires switching versions of other packages, in particular xserver-xorg-core. The difference might actually be there. E.g. it might be interesting rebuilding the Debian driver package against the Ubuntu X server and vice versa and seeing what happens in each case. -- Earthling Michel Dänzer |http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".

I forgot to include this in the report, sorry. I have already tried with the kernel and X from experimental, no different outcome. Only after trying both from experimental did I switch to trying Ubuntu's. Also, once I installed the X driver from Ubuntu, all 3 kernels (Maverick's, Squeeze's and Experimental's suspended and hibernated correctly), so it looks like it's not a kernel problem, it's an X problem. So, newer kernel doesn't help, the kms file is not missing.

The difference is that the preinst of the Ubuntu package removes the file /etc/modprobe.d/radeon-kms.conf (it is not needed on Ubuntu, because Ubuntu kernels are built with KMS enabled), leaving you with UMS even after you reinstall the Debian package. The first thing I would do is to test a newer kernel, e.g. 2.6.37-c7 from experimental, and restore the missing file. > In the logs below, I have removed the messages that were redundant (lines > and lines of the same FBDEV error). > The weird "atom" errors that show in the dmesg logs appear when > hibernating/dehibernating, and are very surprising, taking into account > this is NOT an Atom netbook.

Bug#608616: Mobility Radeon HD 4200: Black screen after resuming from suspend / no-hibernation
Package: xserver-xorg-video-radeon Version: 1:6.13.1-2+squeeze1 Severity: normal Hi! I'm working with an Asus EeePC 1215T, that comes with a Mobility Radeon HD 4200, after installing a fresh squeeze into it, suspend and hibernate didn't work properly: suspend worked, but when returning, no video returned, hibernation didn't work (black screen but no power off). After installing the xserver driver from maverick (1:6.13.1-1ubuntu5), both started working properly. So it seems that there's a difference in the patches applied in one and the other that makes suspension/hibernation work with one and not the other. Before using Ubuntu's packages, I tried blacklisting the radeon module, and it also didn't work. I tried using the radeonhd package, but that left me with no video. After looking at the changelogs and differences between the two packages, I have the sensation that the problem might be related to kms, but I really don't know enough about X to debug this myself. I'm in need of a few extra pointers as to what to do/test next. In the info included by reportbug this (apparently relevant) file is missing: Contents of /etc/modprobe.d/radeon-kms.conf: options radeon modeset=1 In the logs below, I have removed the messages that were redundant (lines and lines of the same FBDEV error). The weird "atom" errors that show in the dmesg logs appear when hibernating/dehibernating, and are very surprising, taking into account this is NOT an Atom netbook. Please let me know what other information I should include, or what other tests I should perform. -- Love, Marga. -- Package-specific info: /var/lib/x11/X.roster does not exist. /var/lib/x11/X.md5sum does not exist.
