No its not a Yatse Problem. When i click Suspend in Openelec the Box stays on nothing is suspend or turning off.
Then i tried to Standby that works well. But i cant wake up over WOL

Never had any issues here. I'd suggest you check the logs to see what's causing it not to suspend properly

OpenElec repeatedly and reproducibly liked to "hang/freeze" on playback with a video freeze while audio was constantly playing but with the new beta builds of OpenElec it got worse to the point where the video file would freeze at some point and you had to restart the box

will try to update SeaBios via script tomorrow. known issue? intel drivers?

https://bugs.freedesktop.org/show_bug.cgi?id=81447 <- intel bug, most likely in libdrm - we will see. They are not very keen on fixing things in the last months.

Updating the firmware or SeaBIOS will have no effect; as noted, it's an intel driver bug. See the notes in the wiki for the optimal settings to work around the issue(s)

Hi all,

I have the celeron chromebox and I installed lubuntu last night and it is very fast.

Had a few hiccups with the audio driver and video tearing. Seems like youtube does not want to exit full screen when i enable the tearing fix in xorg.


Does anyone know how to get the GPU acceleration working, my daughter wants to play minecraft and it seems really really slow, or is the intel HD graphics really that bad?

Also how can you tell if HW video acceleration is working in mplayer of vlc?

Thanks.

Nothing appears in the log. its like.. the button has no command. u got also 4.1.2?

I'm using this now in Xubuntu but it will work in lubuntu also. With this it fixes the tearng and graphic corruption

updated the wiki with some info on properly setting the color range, as well as a potential fix for those people having audio issues upon wake from suspend.

Still no problems with audio since fix here. Thank you!

Matt: I tried this and it did not work for me. Is there a way I can debug if autostart.sh is actually run when I resume from sleep? I added a line that writes the time to a log file, and I don't see that log after resuming from sleep.

jsp1: which fix are you referring to here? Is this something different than Matt's xrandr note on the wiki?

Afraid that was the fix I was referring to. I didn't post a follow up that I still ran into problems here and had just been especially lucky after applying the fix and had 8-10 resumes without an audio failure. Unfortunately, the fix doesn't seem to work in all cases. Sorry for not updating about that and getting hopes up. I have a feeling you are correct and that autostart.sh only works on a fresh start or reboot. I wonder if it could be scripted to somehow run on resume?

I did however, find that if you are using a harmony remote and you change up the CB power to last in the list and add a much longer delay 8-10k ms for example then you can mitigate the chances of dropping audio significantly. In my opinion the box simply resumes too fast for some AV receivers to be ready to receive a handshake properly. Since the audio device isn't something you can "keep alive" during a suspend state (especially if the AV receiver is down) then you need the script to wake it up on a delay in such a case, even if the autostart.sh is running on resume.

My main use will be to stream movies and TV shows over WiFI. My wireless router is not very far away (20 feet) but a wired connection is not really an option with how my basement suite is set up. I have been using an OUYA for almost a year now and while it works fine for the most part, there is a whole lot of room for improvement.

I've played with streaming a bit using my wifi connected Chromebox XBMC/OpenELEC as the source. Have so far had no luck with streaming video to my Wife's Nook HD+ (music works so the problem is on the Nook side of things), but I've got it working to our Ubuntu 10.04 quad core desktops using djmount as mentioned in this thread: http://forum.xbmc.org/showthread.php?tid=135507 as a test to figure out if the Chromebox video streaming was OK or not.

My desktop has a gigabit wired ethernet connection to the ASUS 802.11AC wireless router. With VLC I can play 13 Mb/s 1920x1080 60i videos recorded with our Hauppauge HD-PVR just fine. My wife's desktop is connected by 802.11N wifi and it drops about 100 frames in 6000 with VLC, and is very noticeable in high motion scenes.

My conclusion is wifi source and wifi client will be problematic with HD videos, but wired to wifi or vice-versa should be OK. Its been a real long time since I've used a single monitor desktop.

Does anyone know if you can drive multiple monitors on the chromebox?

Sorry I missed the context, I was wondering how a second monitor could be useful with a dedicated XBMC setup. Maybe if all the things you can make "popup" when a video was playing would automatically go to the second screen instead .... But I'm starting to think about a second Chromebox just to play around with, I've been very impressed with the price/performance, and over the years ASUS hardware has always given me great service life and bang/buck value.
