Ubuntu Multimedia :: IVTV And (pvr-350) - Permissions Get Reset Everytime When Reboot
Oct 22, 2010
I have hauppauge pvr-350 which has an mpeg2 decoder with an RGB and s-video out to let me send video to my tv. I'm using the ivtv drivers which work well. To test the card I ran
Code:
cat test.mpeg > /dev/video16
-bash: /dev/video16: Permission denied
So then I did
Code:
ls -l /dev/video16
crw-rw---- 1 root video 81, 5 2010-10-22 12:21 /dev/video16
sudo chmod a+rw /dev/video16
[sudo] password for patrick:
cat test.mpeg > /dev/video16
However the permissions get reset everytime I reboot. Is there any way to pass an argument to the ivtv driver to change the default permissions?

My screen resolution keeps reverting back to the default resolution 800x600. I'm using ubuntu 10.04, but had the same problem on 9.10 on my Acer Revo r3600 ION. I am able to change the resolution to 1280x1024 but have to do it by the nVidia configuration tool. The tool then allows me to 'Save to X Configuration'which it appears to have done successfully.See the sections from my 'etcx11xorg.conf' file. This is the state of the file after a reboot by the way.how I can get my desired resolution to persist after I reboot?
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Samsung SyncMaster"
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0
Option "DPMS"
EndSection

I've been having some issues with my sound for a few weeks. Every time I reboot, my sound is muted. I have to open up alsamixer every time and unmute it manually. It is not the "master volume" that is muted but instead the "speaker" volume is the one that is muted. This started when i started up my computer and the ubuntu log-in sound started playing extremely loud. I quickly tried to turn down the volume while it was still booting and ever since then, i have been having this issue. Also, the volume control on my laptop no longer works, even after i adjust the volume with alsamixer. It still shows on the screen that the volume is being adjusted, but it does nothing. I hoped i explained this well enough for someone to be able to help me with this issue. Also, sorry if this issue has been posted before.

After a regrettable typo, I reset all the permissions in my filesystem. What is the easiest way to restore my permissions to how they were? Is there a list where i can find the recommended permission settings for each directory?

I am using a fresh Ubuntu 9.10 installation with english-only language but with a German keyboard.
So, once booted into my (only) account, I use the Keyboard Preferences app to change my Layout from US to German. Which works. I also remove the US keyboard so that the only layout left is German.
But upon a reboot, not only the US kbd is back in the layouts list, but the kbd also has defaulted back to US, so that I have to open the Kbd Prefs to again remove the US layout to get my German layout active again.
I also tried "Apply System-wide" and even logged in as root to make the same changes, but the system always goes back to US layout after a reboot.
This is also a problem when logging in after a reboot - I want the system to use German layout there, too.
So, how do I change the layout globally so that even at the login page I have my German layout already active?

A few hours ago I upgraded my system, from Karmic to Lucid and I'm glad with it.But I have a problem, (two actually, I posted the second in other thread), Gnome is not remembering my Visual Effects configuration. I mean, I select the "extra" option and when reboot, it's back to "none".It will be a pain having to edit this every time my laptop starts.

after the 5.6 update I started loosing the connection to my router. Having had issues with routers before I assumed that the router was on its way out. However I happended to have a laptop handy the other day and thought I would give it a try (after eth0 went down), router was fine(same cable too). I have tried bringing eth0 up/down (gui and ifdown/ifup) and restarted the network(gui and cli) but it will not get an ip(as I recall it does recognize that the cable is connected). If I do a reboot, eth0 comes up immediately. The log just shows repeated dhcp requests. I tried a dhclient -r but it errors out with no link found. It has been doing this since 5.6 came out (roughly once a day) so I THINK that it is not a hardware issue(should have died completely by now if it was). PSU voltages show stable and unchanged. It does use the forcedeath driver. 5.6-64bit fully updated.

I was curious if anyone has addressed this issue before. I have set the permissions to /var/log/Xorg.0.log as follows:
Code:
-rw-r----- 1 root root 00000 Jan 00 00:00 /var/log/Xorg.0.log
I have done a lsof and the file is being opened by root. I have set Roots umask to 0077, yet after a reboot

I have a Centos 5.3 desktop that I have a development board connected via a serial connection to. The permissions on /dev/ttyS0 are currently set
crw--w---- 1 root root 4, 64 Nov 4 13:56 ttyS0
I have changed them so that they read
crw-rw---- 1 root uucp 4, 64 Nov 4 13:56 ttyS0
But every time I initialize the dev board the permissions switch back to the original state. I have found lots about preventing the permissions switching back upon reboot but that doesn't appear to be the problem.

I'm using Ubuntu 9.10. Recently after an upgrade my Ubuntu started running in low graphics mode. After searching through forums, I could finally fix it.I'm not sure what exactly fixed it. I first changed the window manager to metacity. Run the following command:Code:sudo nvidia-xconfig --composite --render-accel --add-argb-glx-visualsAnd then changed window manager to compiz and desktop effects could be enabled.The problem is, everytime I reboot, its again running in low graphics mode, desktop effects cannot be enabled, and I have to do all the troubleshooting again! Any idea how to permanently fix this?EDIT: I found that the graphics is reset even without typing the command everytime. But I still have to switch back and forth from compiz window manager to set it all right!

I upgraded from fedora 14 to fedora 15 yesterday. I live in India (IST) which is GMT +05:30. Every time I boot, my system clock increases its time by 5 and a half hours. For example, system clock on my machine is now Wednesday May 26,2011 22:44. If I were to reboot now, the time I would get is Thursday May 27, 2011 04:14. How do I correct this?

I installed Open Suse 11.3 LXDE from the live CD I downloaded. My monitor settings reset to the highest resolution on every shutdown/reboot. Other settings like my wallpaper and removing the lock screen on screensaver also reset.
Is this there anything I can do to get settings/changes I make to stay?

I'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb.
The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again.
Is there some good solution to reset the camera without rebooting to make it work again?

I recently upgraded from 10.04-11.04 using the 11.04 CD I don't use any effects, I log on the sessions using Ubuntu classic (no effects). Whenever I try to play a video, the gdm restarts and puts me back at the login screen. I installed vlc thinking it might help but no deal.
*edit* I tried all different types of video outputs in vlc, the default seems to work the best, but as soon as I click the vlc window, try to resize it, or access any menu on vlc or try to fullscreen the video gdm crashes and restarts.

Is it possible "reset" all (X, GDM related) permissions/settings of one user? What would cause one specific user not to be able to log into anything via gdm/the login screen? After providing the proper password, the screen goes black and then jumps back to the login screen. No session alternative works, not even xterm or gnome failsafe. I can however log in via the console (Ctrl+Alt+F6, recovery etc). With another user I can log in via GDM just fine, and deleting and re-adding the "broken" user doesn't make any difference.
Some (maybe) relevent logs:
part of syslog:
Quote:
Dec 12 01:20:58 <specific user> pulseaudio[1358]: core-util.c: Home directory /etc/timidity not ours.
Dec 12 01:20:58 <specific user> pulseaudio[1358]: lock-autospawn.c: Cannot access autospawn lock.

I'm unable to reset using either the reset option in gnome shell or the command using a terminal. When I select it the shell exits and displays the graphic "exploding" and then it just sits there. Shutdown works fine; just no reset. Any ideas? I've installed from the DVD. I booted the live CD and it resets just fine so I know it's no my hardware

I am using mplayer with vdpau enabled in Ubuntu 10.10. It works very well in general, reducing cpu usage for hd from 50% to 60% to around 10 -15% or less. There is however one slightly annoying problem. It is that mplayer would appear to "forget" its vdpau output setting once in a while and especially after rebooting. When that happens it needs to be "reset" in order to use vdpau. "Resetting" basically just means opening gnome-mplayer and change video output to xv and then back to vdpau again.
I should clarify that the setting has not actually been lost, it still says "vdpau", it just need resetting).
