One year ago I provided a gentoo ebuild for mplayer which included support for quad-buffered stereo, enabling mplayer to display stereoscopic movies like the great movie Avatar3D I watched in cinema today. To learn more about the movie look here and here. Sadly the patch I referenced there does not apply over newer mplayer versions. So I had to modify the original patch from Stuart Levy to work again with newer mplayer versions. You may download the updated patch from here:

[download#35]

New version available!

The patch should work at least with nvidia quadro boards, probably with some others. It can be used with CRT and generic shutter glasses or HMDs like the Vusix VR920. Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I also modified the mplayer ebuild from portage to include the patch. The modified ebuild is available here:

[download#36]

New version available!

The older ebuild is still available on mygnu.de.

To use the ebuild it just copy it to /usr/local/portage/media-video/mplayer and copy the the patch to the “/usr/local/portage/media-video/mplayer/files” directory.  You probably have to create these directories. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc4_p20091026-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy the experience in the 3rd dimension again.

Today I patched the  brand new zen-sources-2.6.31-r2 with tuxonice. Again it required the modified tuxonice patch of my last ebuild.

Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Download the zen-sources 2.6.31-zen2 patch here: zen-sources.org. Then apply the patch to vanilla kernel sources. Afterwards download my modified tuxonice patch from here: [download#29]. Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from [download#33] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge zen-sources-toi and buld the kernel as you wish.

Tuxonice is not officially supported in zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org. You are on your own.

For my Precision M65 I used the following kernel config: [download#34]

All Information regarding the iwl3945 driver, the aha152x pcmcia scsi card and cpu undervolting in my last post on zen-sources-toi still apply to this version.

For more information on the zen-sources patchset see www.zen-sources.org.

Today I patched the  new zen-sources-2.6.31-r1 with tuxonice. This time it was a bit more complicated since the two patches are conflicting. So I modified the tuxonice patch to apply cleanly over the zen-kernel.

Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Download the zen-sources 2.6.31-zen1 patch here: zen-sources.org. Then apply the patch to vanilla kernel sources. Afterwards download my modified tuxonice patch from here: [download#29]. Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from [download#30] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge zen-sources-toi and buld the kernel as you wish.

To work around the black screen problem with some nvidia-drivers versions occuring with 2.6.30 kernels, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Most probably this problem persists with 2.6.31. Strangely the issue did only occur on my Precision M65 with a Quadro FX350M. It did not occur with the Quadro FX3400 in my Desktop PC, Nvidia-drivers-185.18.31 are running there without any problems.

Tuxonice is not officially supported in zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org. You are on your own.

For my Precision M65 I used the following kernel config: [download#31]

If you want to use all channels with the iwl3945 driver change the line static char *ieee80211_regdom = “US”; to static char *ieee80211_regdom = “JP”; in the file net/wireless/reg.c.

If you also own of those old 16 Bit Adaptec pcmcia scsi cards using the aha152x_cs module you might want to enable it also for 64 Bit kernels. It was masked for 64 Bit kernels somewhere before 2.6.13. I was unable to find out the reason for this so I tried to compile the module. When I insert the card, the module loads properly. Since the drive I could test it with, is currently attached to another box and in use, I can´t try it out for the moment. Once I tried I´ll keep you updated.

To enable the driver remove the line

depends on !64BIT

in the config PCMCIA_AHA152X section in /usr/src/linux/drivers/scsi/pcmcia/Kconfig and select the module in menuconfig.

Addon: I tried a SCSI cdrom with this and it works perfectly. I just filed a bug on this on bugzilla.kernel.org and hope for the driver being unmasked for future  64 Bit kernels.

If you are using this kernel on a notebook with i.e. a Core2 CPU you might be interesting to undervolt your CPU to save power and to produce less heat (keeps the fan off longer). This works like a charm on my M65. Information on this topic can be found here: aldeby.org. The linux-pch patch mentioned there is already included in zen-sources, thus you only have to perform the userspace part begnning at (3).

For image compression in tuxonice include Compressor lzo in your suspend2.conf file.

Sadly the iptables mirror target I published here does not work anymore with the 2.6.31 kernel. A newer version will be available soon on mygnu.de.

For more information on the zen-sources patchset see www.zen-sources.org.

Today I patched the brand new zen-sources-2.6.30-r4 with tuxonice. This was necessary since I need tuxonice on my notebook for suspend modes and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

I recommend using this version over using the r3-version, because it fixes the root exploit vulnerability mentioned on www.linux-magazine.com.

Download the zen-sources 2.6.30-zen4 patch here: zen-sources.org Then apply the patch to vanilla kernel sources. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/current-tuxonice-for-2.6.30.patch-20090620-v1.bz2 and apply it.

For Gentoo users there is a more easy way:

Download my modified overlay (including the patches) from [download#26] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY="/usr/local/portage"

Then emerge zen-sources-toi and buld the kernel as you wish.

Some days ago Thorsten wrote TuxOnIce is broken in 2.6.29-zen1. Well, I wanted to have a 2.6.29 kernel, because the iwl3945 driver in 2.6.29 works the first time with a useable speed for me.  So I no longer need the hack for the ipw3945 driver I published on ipw3945 unter linux-kernel 2.6.27.

Today I managed to patch the brand new zen-sources-2.6.29-r3 with tuxonice. This was necessary since I need tuxonice on my notebook and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Since 2.6.29-zen3 has not been released as patch yet, you may download the patch I created from git here: [download#16] Then apply the patch to the vanilla kernel sources available from kernel.org. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/tuxonice-3.0-for-2.6.29.patch.bz2 and apply it to the kernel sources with the zen patchset already applied.

For Gentoo users there is a more easy way:

Download my modified overlay  (including the patches) from [download#17] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY="/usr/local/portage"

Then emerge zen-sources-toi and buld the kernel as you wish.

The files above are not from an official zen release. Tuxonice is not officially supported in zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org.

For my Precision M65 I used the following kernel config: [download#18]

If you want to use all channels with the iwl3945 driver change the line

static char *ieee80211_regdom = “US”;

to

static char *ieee80211_regdom = “JP”;

in the file net/wireless/reg.c.

Experimenting with my VR920 3D stereo glasses I found a patch to enable stereoscopic support in mplayer (thanks to Stuart Levy). With this patch I can now watch 3D movies on my eyewear under linux. Let me tell you, it’s a really cool experience.

The patch should work at least with nvidia quadro boards, probably with some others. It can also be used with CRT and generic shutter glasses. You can download the patch from here:

mplayer-stereoscopic.patch

Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I modified the mplayer ebuild to include the patch. Download from here:

[download#2]

To use it just copy the mplayer subtree from the portage tree to /usr/local/portage/media-video/mplayer and remove the ebuilds. Copy the new ebuild to that directory and the patch to the “files” directory. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc2_p28058-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY="/usr/local/portage"

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy a new experience in the 3rd dimension.

Addon: Updated modified ebuild for the new version in portage tree:

[download#4]
