Ubuntu Multimedia :: X Becomes Unresponsive When Playing Flash Video In Browser

Oct 23, 2010

I have an ATI 4650 HD and using flgrx via jockey, on 10.10.X becomes unresponsive when I play flash videos inside a browser. The image freezes, and the audio track loops, with a loop length of around 0.5 seconds. The only thing I can is reboot my computer. The xorg log file contains no indication that something went wrong. The last entries in it are the monitor display modes.

I cannot switch to the open source ATI driver, as my monitor screen goes blank after booting.I have tried a fresh system install, but that hasn't worked either.

Ubuntu Multimedia :: Image / Photo Editor - Adjust Color - Crop And Resize

Sep 17, 2010

MS office 2003 came with a prgram called "Microsoft Office Photo Manager". It was a surprisingly lightweight application that could adjust color, crop and resize photos. Very simple interface, easy to use. Perfect for simple modifications to digital photos. Is there anything like this in linux? Gimp is certainly not it. Office Drawing and F-Spot photomanager are not it either.

Ubuntu :: Can't Adjust Display Brightness

May 28, 2010

Ubuntu 10.04 lucid with gnome-power-manager installed on a HP elitebook 8530p. FN keys and desktop display applet will not adjust the display. when I first boot my display is pretty bright with either it plugged into ac or not until i either plug or unplug for the first time then the display dims some, but will not get bright again plugged or unplugged, also /proc/acpi/video/DGFX/LCD/brightness shows it set to 100% at all times it never changes. I'm using the ati driver tried running aticonfig --acpi-services off, but it made no difference. It worked fine in karmic and ibex. I'm out of ideas on how to fix this one. Can anyone point me in the right direction on what to try next?

Fedora :: Adjust Screen Brightness

Mar 13, 2011

Running F14 on Dell Studio 14 with LCD screen and US keyboard selected. After initial power on the keyboard selection of "Windows Key" + F4 will dim the screen and the "Windows Key" + F5 will brighten the screen. When being used, either combination will also show a meter on the screen to display the adjustment of the brightness. When the lid is closed the computer is set to suspend by default. After the computer is brought back from suspend the keyboard short cuts no longer control the brightness and the meter does not appear on the screen. I have not found any other way to control the brightness and I have to restart to get the keyboard short cuts to work again.

Debian :: Can't Adjust Screen Brightness Using Fn Keys?

Nov 24, 2015

When I first install debian I couldn't change the screen brightness at all not manually nor with function keys, but I tried some of the solutions I found on the internet and now I can change the brightness manually (from the power management or the battery icon) but when I use the function keys it takes them like 2 to 3 minutes to respond and cause the system to hang (even mouse curser not responding) and then I'm forced to manually reboot the system, here is some information :

Code: Select all$ ls /sys/class/backlight/
acpi_video0  intel_backlight
Code: Select all$cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

[Code] .....

And I've tried this:

Code: Select allsudo -i kwrite /usr/share/X11/xorg.conf.d/20-intel.conf

And I add the following in this file

Code: Select allSection "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"

Fedora :: Adjust LCD Brightness (backlight) From Command Line?

Jul 10, 2010

I'm writing a script to toggle LCD backlight on my laptop between minimum and previous/current level. I will then assign this script to a button. For this I need to be able to adjust backlight by using some command line utility. Also, this must be possible to be performed by a regular user.

What I have already tried:

1) The "xbacklight" utility. This didn't work. Program reported something like "no outputs found".

2) Used "acpitool -l <backlight_level>". This didn't work either.

3) The "echo -n 100 > /proc/acpi/video/VGA/LCD/brightness" works only when I am root. Changing permission of the file to allow writes by a user only valid until reboot. After reboot I need to change permission again, so this approach is not good either.

What works on my laptop, but with GUI:

1) Adjusting LCD brightness in "System->Preferences->Power Management" works.

2) Adjusting brightness with Gnome Brightness Applet works. However, after changing brightness with applet it says "Cannot get laptop panel brightness" and shows red crossed circle icon. Even after applet shows this message, it is possible to change the backlight level. It seems like the brightness level cannot be retrieved by the applet/system, but it can be set.

I can see that it is definitely possible to adjust LCD brightness through software because of the 2 things above, but how do I allow any user to change it from command line?

So, what are my other possible choices for changing backlight from command line?

General :: Unable To Adjust The Brightness Of The Netbook Screen?

Apr 19, 2010

Long, sad story made short. I have a Samsung Netbook running Windows XP Home, SP3. I set it up to dual boot with Ubuntu, just so I could play around with Ubuntu. Well, Ubuntu started giving me trouble: my internet connection went south, I was unable to adjust the brightness of the Netbook screen, etc., and when I looked for troubleshooting help on the internet, it was all Greek to me as it involved working with Terminal.

I did a search for removing a partition in Windows XP and found "How to use Disk Management to configure basic disks in Windows XP" on the Microsoft and followed the instructions there.

Ubuntu Multimedia :: Video Color Is Very Blue?

Aug 16, 2010

I must have inadvertently changed a color setting in Ubuntu. Suddenly, the color in all video that I play is distinctly blue (human skin is shades of blue and green). This happens to multiple videos in both VLC and Movie Player. It does not happen when I play the same videos on VLC in Windows. Pictures and all other graphics appear completely normal. I am still quite new to Ubuntu and I've never encountered anything like this before. I have no idea where to start
