Ubuntu Multimedia :: Maverick 10.10 Gnome - Compiz - Screen Dims If Bad Keyboard Input - Ex - Del Key
Dec 14, 2010
Running 10.10 with compiz and gnome
The whole screen goes dim for any of the below examples. running "compiz --replace" fixes it until any of the below happens again. When the screen is dim, a new window opened (ex: firefox new window or a new gnome terminal) is full brightness while the rest of the screen stays dim.
Following causes the screen to go dim: In the screen saver - hit the delete key to backspace when the password field is empty. in firefox - ^f to find on a page - start typing and as soon as the find field has text that does not exist anywhere on the page "Phrase not found" the screen dims. in gnome terminal - the profile has the terminal bell checkbox ON - hit backspace on a bash input line with no text on it.

I have enabled compiz on my mum's 64 bit Ubuntu desktop. It works well, but the screen dims significantly once I click the mouse button to rotate the cube. Releasing the mouse button brings the screen brightness back to normal. Is there a setting that controls the screen brightness whilst rotating the cube?

This is a bit complicated to discribe because I don't know the cause, but this problem has been happening for some time (over a few years and generations of kernals), with different Gnome distributions, including Ubuntu (and family) and Fedora. When using Gnome (and only Gnome), I frequently see the screen dim. At the same time, all processes will be locked up. This may happen for a second or two, or it make require a reboot. The mouse can usually move and the underlying program GUIs are still visible, it's just that one or more of the GUIs will be dimmed. This is usually most noticeable with a browser, but that may just be a coincidence.

I got the nVidia driver and Compiz installed. Everything's running fine . But then I tried crtl+alt+F1 - which worked though the font was way too big - and then crtl+alt+F7 to get back to the Desktop but it went to a black screen and blinking cursor instead. I searched a bit and it seems this was a problem a few years back but nothing recent. FWIW, I don't have this problem with Hardy/nVidia/Compiz on another drive in this same machine. Is there a way to fix this?

I'm running a 13" white Macbook. The keyboard worked fine, until today. I logged in and half the keys didn't work, the other half were numbers not the letters they were supposed to be. This started after log in, meaning I was able to enter my password properly: The problem starts when gnome boots up.
By copy and pasting, I installed Kubuntu, where the keyboard also works properly, so this is clearly a gnome problem. I haven't ruled out malicious software, which seems like the next step: How do I verify and replace all the software (gnome) that might be corrupted?

Been using Maverick on my Dell Studio XPS for many months without issue. About a week or two ago, compiz has been acting funny and using a lot of cpu time, making everything "choppy," especially after resuming from suspend. I've googled and searched the forum, but all the related posts seem to be several years old.I tried selecting the previous kernel but it didn't help. Was there a bad update to compiz or ati graphics?
My info:
Code:
> lspci | grep VGA
21:02:00.0 VGA compatible controller: ATI Technologies Inc Madison [Mobility Radeon HD 5000 Series]
> grep -i driver /etc/X11/xorg.conf | uniq
Option "VendorName" "ATI Proprietary Driver"
Driver "fglrx"
[Code]...

Running natty. Main user account. In Ubuntu & Ubuntu Classic, both gnome, no keyboard or on-screen keyboard input. Compiz & metacity both bad. Mouse okay. Other user accounts okay. KDE okay.
Tracked problem to /home/{user}/.gconf/desktop/gnome/session/required_components/%gconf.xml. Removed file, problem goes away.

I installed Ubuntu a couple of months ago using the Wubi installer.Today, I went to restart my PC, but soon after hitting 'Restart' the computer became unresponsive. I couldn't get any keyboard/mouse input to register on screen, so I did a force shut down by holding down the power button. When I turned the computer back on, I selected Ubuntu from the boot menu. The computer printed some messages that passed by relatively quickly so I'm not sure exactly what they said, but it was something along the lines of "NTFS3: wubibuilder failed to load", and then it went straight back to the boot menu. Tried again and again with no success, so I loaded my Windows 7 install to investigate from there. I found a link to Explore2fs on these forums, so I loaded it up, but it apparently can't locate my Ubuntu partition, or at least I don't see my files. I ran the Wubi installer again to see what it would say, and it tells me that a previous installation was detected, and gives me the option to uninstall. Does anyone have an idea of what went wrong,

I just recently installed Slackware onto a virtual machine(I'm planning on buying a new disc drive and 1 TB HDD with-in the next couple of months and plan on Slackware being my primary OS[right now Mac OS X 10.6 is]), and everything went great.
I then went onto edit the /etc/inittab file in emacs and changed the run-level to 4. I don't know why it's decided that I'd want to boot into KDE when XFCE is installed and in the configuration I selected XFCE but it's not really relevant(I have a WM guide thing open in another tab and will probably be able to change it).
The problem is, as the vague title may suggest, is that it basically freezes when I'm at the log-in screen. The input field for the username is highlighted and blinking, and the cursor it self is visible in the centre of the screen, but it simply doesn't pick up on any input from my keyboard or mouse.
I tried booting up the install CD and logging in as root, mounting sda4(which is the root partition) and editing said file but sudo isn't installed(to my knowledge) on the install disc and when I do the command,

I am trying to get the sounds that are played on the Casio CTK-651 keyboard from the keyboard into ubuntu or windows. I can get the signal, but no sound is played back under Windows when it's connected with an AUX-to-USB connector. When I do it with the MIDI-to-USB connector in windows and ubuntu, whenever I press a key, I get what is programmed into LMMS through connecting in a channel. I can't get the piano or guitar or whatever sound that the keyboard is making into the computer. I can upload some video to show what I'm talking about with the aux connector.

I'm running openSUSE 11.3 with an Intel GM965 on-board video card. After upgrading xorg-x11-server to 7.5_1.9.0-62.2.x86_64 from Index of /repositories/X11:/XOrg/openSUSE_11.3/x86_64 after a suggestion to fix a different problem, I noticed that the screensaver seems to work fine as mentioned above. However, I've noticed now that when the screen starts to dim before applying the actual screensaver I apparently can't cancel the screensaver initiation until after the screen finishes dimming (that is, goes completely black) and the screensaver actually starts. No amount of mouse gestures, clicks or key strokes will cancel the screensaver once the screen starts to dim until the screensaver itself starts running.

Im running suse 11.2 on a gateway lt3103u during boot i noticed the screen goes dim. i thought nothing of it untill i tried to watch *ahem* educational video *ahem*. ive found that no matter what program i use xine vlc or anything else that video sets the screen to dim as if it were in power saving mode. this problem also occurs when i close the lid. it locks the screen into dim mode. in both cases i can use both Fn keys and the power management widget to reset it to bright, but this problem is annoying having to keep turning it back u to see.

I want to record a streaming-audio (not capture), to use an alarm sound. I opened up gnome-sound-recorder, but I don't see input drop-down menu. I tried Audacity, but it's missing the menu, too.I saw the specification sheet of my laptop, but it only says Mobile Intel� GS45 Express Chipsets, I'm not sure if it manages sound, too, but the sheet doesn't have any information about sound chip set.dd: It seems like I can't change this to 'solved'. I cannot say it is solved, as I don't yet see the drop-down menu in gnome-sound-recorder, but with PulseAudio I can perform the task, so it can be regarded as solved?

How to get compiz to auto-start. What seems to be the generally accepted method (from what a few google searches and the debian wiki tell me) of using gconf-editor and changing the window manager from 'gnome-wm' to 'compiz' in desktop > gnome > session > required_components doesn't change anything. The only method I found that did not involve using a terminal and running 'compiz --replace' every time I boot the computer was to add compiz and fusion-icon to the gnome startup apps, but this causes unwanted flickering (it starts metacity and then replaces it with compiz, ie it's simply automating what I would do with the terminal). Autostarting the fusion-icon alone does not start compiz, although it allows me to start it from it's menu if I right click the icon. Note that I sometimes use fluxbox as well, so starting it on boot isn't really an option either.
Perhaps this can be useful :
compiz:
Installed: 0.8.4-4
Candidate: 0.8.4-4
gnome-session:
Installed: 2.30.2-3
Candidate: 2.30.2-3

I have updated my 11.3x64 recently and after updateI cannot log into any X session.Keyboard is dead but mouse is moving fine.I tried to change kdm to gdm - no result!All I can do now is - select by mouse "Console Session"and log in to common terminal. In terminal session keyboard works.I can't understand What is it?The most interesting:If I run terminal as a root and run startx - kde desktop is started but the same way - without keyboard!Hardware manager (YAST) shows: /dev/input/event0and shows type of keyboard right: AT Keyboard bla-bla-bla. (Common Genius PS/2 keyboard for 6$ :-))I suspect something wrong with my X11 but can't get what!I did not find xorg.conf in it's standard place. I have found only /etc/X11/xorg.conf.install

I've heard that Compiz is not working in Maverick. Is this true? Has it impacted computers with decent graphics cards much, or is it no big deal? I'm kinda confused, because of the Ubiquity thing. Is that replacing compiz?

After a few tries, I managed to install Ubuntu on my 3rd generation Macbook Pro (MacbookPro3,1). I installed the proprietary drivers for the Nvidia graphics card and got all the other features working with the information from this page. However, I am having various problems getting the screens working as I would like. When my laptop is at my desk, it is connected to an external 24-inch monitor via DVI, however I regularly disconnect this screen when I go to uni etc.
Ideally I would like Ubuntu to do the following (all of which I can do in Windows and Mac, or the equivalent thereof): Auto-detect when the external monitor is plugged in, set that monitor as the primary screen (with gnome panel etc). And auto-detect when it is unplugged and set the laptop screen as primary.
Support moving windows between both screens Compiz on both screens Separate colour calibration on each screen So far, I have only been able to get a subset of these working at once. I got 2 working alone, without any compiz and the colour calibration only worked on the laptop screen. I got 3 and 4 working without being able to move windows between screens. I have not been able to get 1 working at all - when I disconnect the monitor, I have to tell the nvidia control panel it is gone.
Is there any way to get all four of these things working? I would be willing to sacrifice 3 if 1, 2, and 4 were all working. (I posted this thread to Apple users as well, but I figure there will be more activity here).

I upgrade yesterday my lenny to squeeze.
Now I have some problem with compiz. When I do compiz --replace, I get:
compiz (core) - Fatal: Software rendering detected.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
Launching fallback window manager
Is it a driver problem? My ATI video card is one of them that works only with open driver and they seems corrrectly installed. glxinfo | grep render, give me a positive result.

If I remain 'connected' (with the KVM) to the linux machine the gnome screen saver cuts in and the system remains 'as is' until 'woken up' with the mouse or keyboard. However, if I switch to another machine using the KVM, within a short time (maybe even minute or two) the linux machine goes dead. Now it has not crashed, as I can log in from a remote machine and do anything I need from a terminal, but the machine seems not to respond. I can't even use ctrl-alt-fn to switch to a console screen.
I initially tried entering telinit 3 from a remote machine but it made no apparent difference. However, if after telinit 3 I then killed the Xorg process and later issued a telinit 5 the X server restarted, but with a curious black 'notch' at the top of the screen. I am using an NVIDIA GeForce 7600 GS graphics card. I am now adding the backtrace from Xorg.0.log. It seems that when the KVM switches to another machine for more than a very short time the X server crashes.

I'm running Maverick on an HP dv6 laptop. I tried recording a video via VLC with the machine's 'TrueVision' webcam. The result seemed to lack audio, so I had a look in preferences > sound. The input tab had the mute button ticked, so I unticked it and tried adjusting the level (while realising I was probably just configuring the mic port and not the webcam's inbuilt mics).
Then things turned bad: pointer became sluggish, and changes I made to the level slider took ages to be reflected visually on screen. I queued up a pile of clicks on the 'close' button and went away for a while. On return, I was met with a box inviting me to stop a script with some screen-width-long incomprehensible name, which of course I did.
Now the system's in a state which sees windows missing title bars (tho' not menu bars) and (more problematically) the upper and lower bars on the desktop absent. I issued a hibernate command from the terminal in the hope that on waking the system would be 'fixed', but nothing changed. I tried alt-tabbing to access my open applications and close them gracefully but this command is ignored. I have 'zillions' of apps going with unsaved data and am not sure what to try next. I'd be happy just to be able to task switch to each open prog and exit it gracefully then restart. But my knowledge of the command line is such that your help is required =) .

I have a new install of Karmic on my system with a flyvideo 3000 tv card installed. My problem is that it doesn't find any radio channels and the input channel is completely wrong. I don't have any sound on gnomeradio and can't find the config files to change the input channel. The only input option available to me is dig1 - can anyone point me in the right direction?
I have already read the Howto for this tv card and changed the device to radio0 in the setup. I have setup tvtime perfectly with sound channel as well as with a 5.1 surround configuration. I am missing my favourite radio channel. and I want to get rid of my windows installations once and for all! Update: I did a system update and some things have changed: the radio tower graphic on gnomeradio is now green (I assume it is getting a signal) but no sound yet.

I recently got a real fancy unidirectional microphone, but when I go and use it, something strange happens. The mic is a mono mic, but when I record something, it appears to think it's stereo. Instead of having the same thing on both channels, it puts it all in the left channel, and silence on the right channel.
I tried fiddling with alsamixer. In capture (F4), adjusting the "Capture" device has an effect. However, it doesn't do anything useful. Lowering the right channel to zero does nothing, lowering the left channel to zero creates silence, and disabling the right channel creates silence.
In my System>Preferences>Sound (or pavucontrol, or what-have-you), there are "Analog Stereo Input" and "Analog Stereo Duplex" options there, but no "Analog Mono Input" or "Analog Stereo Output + Analog Mono Input" options (the latter being ideal).
Something interesting, though, if I do this:
Code:
arecord -r 96000 -D pulse -c 1 -vv -V mono /dev/null
it works correctly and outputs on both channels. But if I do
Code:
arecord -r 96000 -D pulse -c 2 -vv -V stereo /dev/null
then it's back to the same behavior. The VU meter on the second command shows the left channel going up and down as I make noise, but the right one always at zero.
The machine does have a crap internal mic built in to the screen bezel. If I do either of the above commands, they both work correctly. The stereo VU shows the same activity for both channels.
The machine is a Eee 1015PED, which has Intel integrated sound. Something probably insignificant is that the mic has a 1/4 inch mono plug, and to get it to plug into the Eee, I needed to get a 1/4 female to 1/8 male adapter. The mic's 1/4 plug is mono (duh) and therefore two-conductor, but the adapter I got is stereo, or three conductor (L, R, GND). I don't know if this is tripping something in hardware to tell it it's stereo or something.
I tried the mic on my desktop, which has a SB Audigy 4 (the non-pro flavor) and that has the "Analog Mono Input" function, so that works fine. Is there some way to turn this stereo input into mono input?
