Ubuntu / Apple :: 10.04 & MythTV Frontend On IBook G4 - No Sound And Video On Playback
Jun 8, 2010
I set up Ubuntu on an old iBook G4, planning to use it as a front end to my main box. Installed 10.04 no problem, and from there, used Software Center to install MythTV Front end. Have done the same thing on a netbook, no problem.
However, on this PPC Mac, the front end works fine, navigation, menus, etc, until I try to play a recorded programme - the screen is blank, and I just get white noise from the speakers.
(BTW am trying Ubuntu as I don't have a Mac OS new enough to get any of the current Mac MythFrontEnd builds working)

After overcomming a lot of difficulties, my MythTV (Via Epia 10000EG with Hauppauge PVR 500 card) worked with Mythbuntu 9.04. Last year it crashed and I had no time to spare to rebuild it.
Last couple of weeks I had more time and downloaded and tried to install Mythbuntu 10.10. Everything seems to be installed ok, but I get no picture in MythTV when I select "Watch TV" and no picture when I try to record something. When watching TV, the message "Please wait" appears for appr. 5 secs and then the system returns to the menu.
I installed Mythbuntu 10.10 and am using the provided IVTV drivers.
Dmesg and lspci give no errors, every seems to be in order, IVTV drivers are loaded, initialized and errorfree. Cat /dev/video0 gives me static in MPLAYER. The MythTV backendlog doesn't even give a message, the frontend log just says there is no picture...
There seems to be an error between the back and frontend. I checked the settings in capturecards, TV sources, channel edits, etc,etc, but I can't find it.

I can't get mythtv to play television with my Hauppauge HVR-850 tv card. I was able to view tv in mplayer, so I know that the card is working. The tv signal is broadcast only (no cable). I had to set the card type to DVB DTV capture card (v3.x) to get mythtv-setup to successfully scan. I was able to successfully scan both with a "full scan" and with a channels.conf file that I had generated earlier when tinkering tv in mplayer. Unfortunately, the mythtv frontend failed to play any live tv. It said "Error: MythTV is using all inputs, but there are no active recordings?"

When I play large HD videos in mplayer, the video and sound frequently get out of sync, and the video plays a little strangely (occasionally speeding up and occasionally slowing down).
I think it's because mplayer is only running on a single core. As I've got a quad-core processor, it seems inefficient. I've seen that there is theoretically a way to get mplayer to work with multicore setups, but it requires compiling with different options. That'd take me a little while to work through.
Ideally there would be a pre-compiled version in the software centre, or a player which has support built in (again, ideally in the software centre). Is there such a thing available?

I've been running F12 x86_64 for almost a week now without significant issues, until now. I found this annoying problem with the audio system during video playback (both with VLC and with Kaffeine).It happens after a while playing a video: sound just stops (video continues). I found that sound is not dead though (can open Rhythmbox and music sounds).I discovered some system messages in /var/log/messages regarding this (attached).What could be happening

No sound on my Fedora when I play stuff on my hard disk. Video plays but there would be no sound. But there is sound/audio when I start using a browser. So I guess flash is working. Any basic trouble shooting stuff for audio? I tried this [URL] but the stuff is way over my head.

I have had some issues since installing Fedora 11 on my desktop (well not after I installed it, once I installed the updates). Anyway sound was cutting out, videos were jumping, speeding up with no sound etc online such as ....., when playing local songs and videos etc. Anyway I followed this guide [URL] and that fixed my playing of online videos, music and when I play local music in totem etc. IN fact there is no issues with sound in those.
However; when I try to play a local video in any medial player it jumps sound, crashes, if it starts playing sound it will cut out and if I move the video forward it cuts out and sometimes crashes the video player. Any ideas why that guide fixed all online video and local MP3 but is till messed up playing local videos?

i'm using ubuntu since 8.04, and the current (9.10) is a fresh install on new hdd.the problem was the same each version (8.04, 8.10, 9.04, 9.10) - while i'm playing the video (no matter if i use mplayer [smplayer], gstreamer [totem] or adobe flash plugin [videos]) the playback freezes randomly for about 5-10 sec. during the freeze the movie is still played, i can hear the sound is ok. if i press [space] in smplayer it pauses the playback, so the responses for keyboard actions are ok. not for the mouse clicks however. i can still move the cursor around the screen but it seems the system is not aware of it (clicking on the "pause" button doesnt pause the movie). except the cursor, nothing changes on the screen (if the im [pidgin] window was blinking because of new message, it freezes etc etc).
is there any kind of log i could look into just to try figuring out the problem?it is impossible to watch any movie on my pc (currently i don't have tv)i installed windows on external hdd once and it played videos fine so i suppose it's not hardware problem .

I'm trying to install ubuntu on an old iBook G4. I have two cds (9.10 (not PPC specific) and 8.04.1 (the PPC specific version)) along with the G4 install cds. I've tried booting while holding down C, and I've tried to boot holding down option. When the boot menu comes up it does not recognize either one. I've also reset the PRAM.I've read a lot of guides, and look through this very thoroughly. I don't even want to dual boot, just Ubuntu.

I thought it would be great to update to the latest version of ppc ubuntu on my old ibook g4, so i did just that. Everything seemed to install correctly, and the broadcom driver was properly detected and downloaded...however...when I connect to my wireless network, I can't get any data flow. No web pages, no connection to empathy...nothing.verything worked so flawlessly in 9.10, and I had just been using the wireless connection before I installed 10.04, so I know the hardware is fine

I have an ibook g3 that I'm trying to resurrect with Ubuntu 10.04. However, booting into live CD always freezes it at some point in the installation process. I got it installed but everything takes five minutes to open. any way to make it faster?

I have an old ibook g4. I was trying to install 10.04 on it. It booted from the cd,but when I installed ubuntu there were 2 or three error messages near the end that it couldnt delete some files. When I restarted, the computer went fine, until it got to a black screen with white text, which said it couldn't find files and said it would reboot in 180 seconds. I let it, and it just ended up the same. Did I trash my computer?

I have been running Ubuntu in my iBook/g4 800, 12' inch screen since jaunty and I must confess that I have had a fair share of graphics issue, however, since karmic, my computer would just go off especially when the AC is disconnected then on plugging back the AC, it comes back on but with the windows or the previous items on the screen completely deformed, that kind of deformation you would only blame graphics for. So the deformation stays for long and a reboot is all I'm left with.While still in karmic, i thought an upgrade to Lucid would get things back in place but that never happened, so I have been wondering what to do. I thought of a key combination that would turn on the screen in an iBook but I cant seem to find that through google, so I'm left with just fixing the underlying issue which according to some post on the Internet, wrong graphics settings might cause the monitor to shut down unexpectedly. I don't know exactly what exactly am I supposed to do? If that post is anything to go by, here is my xorg.conf(I know karmic+ does not need this but my system needs it) code...

so after install several different versions of ubuntu on my ibook g4 I finally got xubuntu jaunty up and running. the problem is it wont update anything when i run sudo apt-get update it fails to fetch anything from the repos. also when i go to aplications software sources it wont let me check the important security updates tab at all.I installed ubuntu hardy on my g4 powermac and that runs just fine but it doesn't work correctly on my ibook so i would really like to stick with jaunty but i cant seem to find a solution.here is my sources.list
# deb cdrom:[Xubuntu 9.04 _Jaunty Jackalope_ - Release powerpc (20090423)]/ jaunty main
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to

So I recently installed Ubuntu 10.04 on my 800 MHz iBook G4 with a Radeon 9200. After messing around with the xorg file, I was able to get compiz working well - but now the only problem I'm having is that scrolling in any window is ridiculously choppy - comparable to scrolling a window of a computer over remote desktop.

I was easily able to install Ubuntu 10.04 (powerpc version) on my old iBook G4 just to see what it was like. After installation, I tried to connect to my Airport Extreme, and it didn't work.
For the past few days, I have been trying to research how to be able to connect to my Airport Extreme, and I have had no luck. Apparently, there is some sort of driver that I have to install called b43-fwcutter, but I have no clue where to find it or how to install it.
Btw, the iBook obviously isn't the only computer I have, so I am able to download necessary packages on other computers, and transport it with USB flashdrives.

I was fiddling with trying to get KMS working for about a week till I realized that it was probably broken and decided to drop it and use userspace DRI. Lo and behold, it was faster than I think I've ever gotten out of this model before. I'm aware that KMS supposedly supports the Mobility Radeon chip in this machine, but until I can find an easy way to get it to work, I'm probably going to stick with UMS. That being said, if anybody can get KMS working, I'd LOVE to change the tutorial around a bit.That being said, I'd like to take a moment to address a few things. This is not a tutorial for all iBooks, or all PPC Macs for Lucid. I cannot stress enough that your mileage may vary, and you should not hold me responsible for your individual situation.

I have an old iBook G3 12" Dual USB (M7692LL/A) with 128Mb extra of RAM.
I was trying to boot Ubuntu from an external USB DVD and a FW CD drive, and the same thing happened. When I select the disc from the boot select screen and press enter, the colors get funky and it stays like that for minutes!

I have an iBook G3 and about 4 months ago after Mac OSX was corrupted I installed Ubuntu 9.10 on it. During the install the screen was divided and partly blacked out but when I installed it, the resolution was fine and the OS encompassed the whole screen.
After a few weeks everything on the screen started to turn pink until all the colours on the whole screen were a shade of pink! I decided that I would abandon my laptop as I had a fully functioning Ubuntu desktop which was my preferable computer to use anyway.
Following the release of Ubuntu 10.04 I decided that I would try a fresh install on my laptop. When I started the install I was disappointed to find that the screen was divided and everything was shaded pink. I went ahead with the install regardless hoping that everything would be fine once I installed Ubuntu. Once again I was let down, the screen was still divided and pink. I have included some pictures for you to have a look at.

I have Karmic Koala 9.10 working (near) perfectly on my iMac7,1, as identified by
Code:
NOTE: See below for Lucid 10.04 update to these instructions
IMPORTANT: You need to complete the installation procedure while connected to internet via the WIRED network. Then you can enable the wireless by installing the restricted drivers, after the install is complete. Also the fglrx ATI Video driver is effortlessly installed via Menu > System > Administration > Hardware Drivers
The sound card gave me some trouble, as it is an Intel HDA Model, reported as 'Codec: Realtek ALC889A' by

It shows up in lspci as:

It sounded rather tinny at first, when I tried mbp3 and other model names. Then I added the following line to /etc/modprobe.d/alsa-base.conf :

After reboot, my sound is full and can be put much louder than before. Jack detection works. Some people might have to leave out the power saving options. See below.

Sources consulted are mostly the kernel documentation ( Enter into the terminal: sudo apt-get install linux-doc

video playback is like I have applied a blueish sepia filter over it. And this is just the playback from totem player or mplayer, and not the playback from ..... (and generally online streaming) - this works just fine. this messy video playback also appears when I use cheese to capture video with my webcam. Note that the preview picture of the video file on nautilus has the natural colours it should have.
at first when I installed the os this particular problem didn't exist, but it came up the time I decided to follow the "comprehensive multimedia guide". So now I have all the pros of following the guide, but this is a major con...

I am setting up a MythTV environment to switch from Windows based MediaPortal (with a high number of disturbing bugs). Yet, I have three difficulties, which I want to discuss with you. They are:
- No audio via HDMI see [URL]
- Video resolution seems to change during video playback
- Channels cannot be found via DVB-S [URL]
As you can see, I have created three posts to keep discussions focused.
Alltogether I have the following setup:
- AMD 5050e CPU
- 8 GByte RAM
- Biostar TA890GXE
- Samsung LE40M86BD, connected via HDMI (and only HDMI)
- Mythbuntu 10.10 with proprietary drivers installed
- Technisat Skystar HD2 DVB-S card (two times)
Now, here is the problem:
Whenever I playback any video material using e.g. VLC, the screen resolution changes. This also applies when playback the video in a window and not fullscreen. The problem is that whenever the screen resolution changes, short time later the TV set blanks screen and show the TV set specific information "unsupported video mode".
How can I enforce to stay in the configured video mode?
