Ubuntu :: 11.04 - User Interface (UI) Disappeared + Compiz & OpenGL - Cannot Control Anything Anymore
May 19, 2011
I blew my UI (Unity) and dont know how to get it back. I wanted to set my Desktop cube using Compiz and selected OpenGL, but this blew my whole UI away and I cannot control anything anymore. From the empty screen I opened the application console using crtl + F2 There, a Login shows up but I do not know how to login (yeah LOLing here too). Username and my Password didnt make it. I could also not setup any new root password there. What data is needed here? Root, Username? Ubuntu 11.04 ubuntu ubuntu Login:
Code: Failed to activate desktop effects using the given options. Settings will be reverted to their previous values.
Check your X configuaration.
You may also consider changing advanced options, especially changing the composting type. I cannot use OpenGL, hence my Compiz is useless.. I have ATI 5850s
The first issue is that none of the screensavers that come with ubuntu that have GL in the name work on my system. They just show a black screen.Of the 13 that came when i first installed the only ones that work are cosmos, fibrelamp, floating feet, floating ubuntu and fuzzyflakes. All the others show nothing at all. Fair enough I thought,I can live with that so downloaded a few games and things. All worked til I tried my first 3d game(oolite). On starting this I am just faced with a black screen and nothing happens. I think that the 2 issues may be related and that its likely to be a open GL issue. I have installed latest AMD drivers and my card(4350) seems to work fine. Edit: Just tried to use visualisations while using Rhythmbox and these dont work either.They show up on screen but cause my system to freeze,so I am sure I have a graphics problem
I'm using currently ubuntu 10.10. Having a nvidia gt220 with the proprietary drivers. I used compiz for a while. It works quite well, with vsync on and so on. But one thing bothers me all the time: In any opengl program (like a game or the unigen benchmarks) or on video playback (no matter if its the default video player, xbmc or what ever) I see some kind of stutter. About every second or so it jumps one frame forward and then two back. Till the next second it plays fluid.
To be able to observe this easily you need a video (or a opengl scene) where the whole screen scrolls in a medium speed but smooth. Than you can observ how it "jumps" every second. If the scrolling is too slow you wont observe it. Now, if I turn composite off this disapears. All play fluid. Ofcourse I get tearing as long as I do not also disable the composite extension in the xorg.conf, but this is another story. Is there a possibility to fix this stuttering with compiz active? Cause I use this pc to watch movies quite often so this would render compiz unusable.
Volume up, volume down and mute keys on the keyboard don't control the volume any longer.They worked before. Hitting the keys brings up a progress bar widget with the volume level unchangeable, set at 0% (which is not accurate at all).It looks like the key mappings or key bindings are working, but there is a disconnect with actual functionality. The volume cannot be changed or muted anymore from the keyboard.
This worked just fine in KDE on Fedora 11 before upgrading KDE components yesterday with Yumex. I am now using KDE 4.3.2 I don't think that it's a coincidence that it stopped working after doing an update. I updated the kernel and nVidia drivers too, but this problem exists when I went back and tested with the previous kernel, so I don't suspect the kernel upgrade. No info in Xorg.conf about the keyboard. Is there a setting that I am missing?
Sound works just fine. I can listen to whatever source I like. This is not a problem with the sound drivers as far as I can tell.I just want to be able to control the volume with the keys on my Logitech Illuminated Keyboard, model Y-UY95. Is anyone else experiencing this?I can adjust the volume with Kmix 3.5 or GNOME Volume Control V2.1
So I JUST got back to Ubuntu and got my installation all up and running, but Compiz has apparently changed a bit as my desktop cube is not what it used to be. On 9.XX, 8.XX, and 7.XX; I clearly remember being able to make the Windows on each cube face appear to be stacked, however I cannot find this setting ANYWHERE in the new compiz menu.
right now am posting this from ubuntu safe mode, when i login normally what i get is just a plain space without desktop alt+f2 also not working there, only thing i can do from there is ctrl+alt+del and a window came without borders and i can restart or shutdown pc.
i had installed compiz configuration window and tried to enable cube desktop and it showed some conflict with other plugins and i had pressed disable this plugin and all tick mark in that configuration window gone after that this problem occurred
I've done a new 10.04 installation and downloaded CCSM but I can't find the option to turn the rotating cube (all options present and correct) into a rotating sphere.Have I just forgotten to download some additional plugins or similar?
after installing trying to install veetle on my ubuntu 10.04 64 bit I always get the message at the start-up:could not update /home/user/.ICEauthority.my sound control does not work anymore (message: 'waiting for sound system to respond')using Krusader I get the message 'Cannot talk to klauncher: The name org.kde. klauncher was not provided by any .service files.I checked the owner of .ICEauthority and the permission and they are OK. Same for my /home. None of the suggestions found in the other threads worked.Veetle has been installed using the install.sh script and there is no unistall option
when I upgraded to xubuntu 9.1 I was pleased to find a mixer control sitting in my notification area.well, yesterday I was doing a little "house cleaning" and removing apps I didn't use. I removed Brasero, Listen and Sound Recorder. I use xfBurn, Banshee and Audacity. now I notice today that I am missing the mixer control that I had like so much. still have xfce4-mixer, but all the controls have been reset. and I can't get it to minimize/close to the notification area
Because of a horrible problem (volume bursting, this is known bug), I completely removed Pulseaudio and some related packages. So I'm now using pure ALSA, and it's working fine. Yet, the volume control tray icon was disappeared. How can I recover it?
I want to find a way to control compiz from my panel, basically have some custom launchers that would say rotate cube or bring up expo, i have been unable to find commands to do this, does anyone know if this is possible. even if it were a link to a bash script.
I have a user account which is required to run as part of the operating system and as a service. I am currently attempting to install my companies software on an Ubuntu desktop via wine just for the purpose of finding out if it's do-able.
Is there a way, in Ubuntu, for a user account to be given the local rights assignment to act as part of the operating system and to function as a service in the background?
I want to set up a home computer as server. I've installed Ubuntu Server Edition 10.04, and can access it through SSH. However, I would like to have a browser based interface for managing things, such as installing a phpBB forum and stuff like that. Also, I want my friends to be able to share files on my home server as well. I know I can do it by using FTP, but I would rather not have them to install a FTP program.
I just built up an Acer Revo 3600 HTPC using Ubuntu. Right now I'm using a wireless keyboard and mouse but I'd like to get a remote control to interface with XBMC. There seem to be many remotes that work under windows but I am having a hard time finding a remote that works with Ubuntu. What are people using to control their Ubuntu-based HTPCs these days?
Im running a dual monitor setup in gnome, with the closed nvidia drivers in twinview mode. most of the times i want to be able to maximize windows to a single monitor (this is the default behavior in 10.04 lucid i believe), but sometimes i want to span a window on both screens. compiz doesn't allow windows to resized past screenborders, and gdevilspie wasn't able to get past this.
After a lot of googling and toying around i came up with the following sollution, i'm posting it here so other people can enjoy it as well (and i'll be able to find it again after my next install).
I made a script to switch between the streched mode and the doublescreen mode to use it, you'll have to stop the autodetection of the outputs in compiz. this option is found in compiz config settings manager under general settings > display settings or though the gconf-editor in /apps/compiz/general/screen0/options/detect_outputs
This script switches between the two modes, but you need to edit the resolutions of your monitors! (i have a double 1280x1024 setup)
Code:
My way of using this: 1. use the script to switch to the span mode 2. start photo/video edit software 3. work 4. close the software 5. use the script to switch back
I have Compiz Config Settings Manager installed on my Ubuntu 10.04 machine. All the effects are working properly and everything is running fine. However when i play video with VLC Media Player, i would only get audio and no video. After looking this up i changed the output to X11 vidoe Output. I started getting video and audio. But when i switch to fullscreen mode the fullscreen video window is rendered by Compiz and thus has all of those window effects like wobbly, minimize, maximize and stuff are also applied to the full screen video. It also does not have all those controls that vlc normally shows when you wiggle your mouse in full-screen mode. I tried disabling the Video Playback option from the CCSM window, but to no avail.
The same thing also happens for the full screen view of Google Chrome. And the only way to leave full screen is to press F11 again. In this case the tab stacking area which drops down doesn't appear at all, also the exit full screen option which too drops down also does not appear. It seems Compiz is blocking all of those interactive buttons like the floating control panel in VLC and Tab stacking area in Chrome.
We are making an embedded product based on Fedora 10 (this could change, but right now we stick to 10 because it works ok). We have an intel PC board with a build a normal ethernet adapter. Then we have a home build PCI-express card with 4 ethernet adapter build into a Xilinx FPGA (Xilinx Temac) (we got the driver from git.xilinx.com and modified it enough to make it work).
Now, by problem is: How do we control the device names of these ethernet adapters? It would be really nice to have them called eth0, eth1-eth4 in the order mentioned above, such our software always knows which to use for what.
Also: What to we do when the our adapter card is replaced because it is broken? A new card will have new MAC addresses and therefore the adapters will get new names destroying our IP configurations.
I just upgraded from FC8 (32-bit) to FC11 (64-bit). In doing so, I backed up my entire World of Warcraft folder so I could try to avoid having to download and install it all over again. However, I've now reinstalled wine (64-bit now), and the nvidia drivers from the rpmfusion repos (also 64-bit), and when I try to start WoW, it says it cannot load OpenGL. I'm wondering if anyone knows what's up, and if there's a solution that doesn't involve reinstalling WoW.
since using 10.04 I have a big problem with my usb headset (freetalk everyman)
1. Problem: I cannot regulate the volume of the phones (output) anymore with gnome-volume-control. By default the volume is set to 100% which is way too loud. When I set it under 100% there is no sound at all. Values over 100% work.
2. Problem: The X server is freezing iregulary when I connect the headset and disconnect it, Magic SysRq works. I checked Xorg.0.log and found out that it recognizes the usb headset as keyboard:
I run both Mac OS X and Lucid. I backed up my OS X partition in preparation for a restore. I also moved over important work documents to Lucid. Restored OS X using timemachine. Updated OS X with patches and moved over some files from external hard drive. After moving the files over, timemachine backed up system. I went into Time machine to transfer work documents over but the previous back up was deleted for the new one. I had the documents on Lucid. I just needed to switch it over to OS X. Therefore, I tried to enable read/write from Lucid to Mac OS X partition.
OS X was unmounted prior to entering commands and performed the steps above under a different user. During step 3 I received an error stating you do not have sufficient privileges and the process stopped. I logged out of my temporary account and tried logging back into my main account. Main account was not present on the login screen. So I followed these steps to change my UID and GID from 501 back to 1000. Login appeared. I tried to login but there was an error about ICEauthority and Nautilus. System doesn't load up and only shows wallpaper. I haven't deleted anything and I expect that I just need to point my UID back to wherever my home folder is.
recently installed ubuntu 10.10 on a new clean pc and added to laptop to run along side windows, solved a few installation issues on the laptop. the pc was running great up to 2 weeks ago, now kernal lost, have busybox inframfs, researched ubuntu forums tried numerous things grub menu, help list commands, reloaded from live cd/usb etc etc and have done my head in, info overload, haven't looked at programming info since 13 on commodore 64's Is there some one here in melbourne who is willing to have me bring the hardware to your place to help get it running again
My desktop won't come up automatically now on a hard disk of mine (see below for the Ubuntu version history). It does boot up with Grub etc; then the Ubuntu load up bar thing with the timer spinning around [I hope you can understand this technical language!] goes through ok but then instead of getting the user interface with the little boxes to enter my login and password, the whole screen is in black (as if it's in Terminal mode). This black screen then asks me for my login and password: when I entered them, it said:
Starting up......loading, please wait 19 + 0 records in 19 + 0 records out kinit: [followed by a load of technical stuff and a series of numbers] kinit: trying to resume from /dev/disk/ by-uuid/9b [then a whole series of numbers] kinit: no resume image, doing normal boot.
when I log in, I can move the mouse, but nothing else. The whole user interface is unresponsive and absolutely no keystroke works. It is probably not because of my hardware (hp 2710p) because logging in as root (with only slightly different Gnome configuration) does work well. I assume it is because of some error inside the Gconf. There is always an error when starting Gnome that an entry could not be read, including some bunches of ~30 question marks. If it is useful, I can give you the whole message literally.
I haven't changed data inside Gconf, but I did have it open when I was installing a program, and then the console did show the message with the question marks for the first time (while processing some "trigger" post-install). I think the program I was installing was drapes (for changing desktop wallpapers in Gnome). Strangely Gnome did startup correctly afterwards for a couple of times (always showing the above-mentioned error). I have no idea what change made it suddenly stop working yesterday.
The differences in Gnome configuration between the working root and the unresponsive user account are, as far as I can tell from memory: changed theme (elegant-brit), wallpaper, fonts, globalmenu in the panel, installed - added to panel - uninstalled drapes.The rest is the same for the root account. I can still log in to the shell as the normal user, but "startx" leads to the disabled graphical interface. As I said, the graphical interface works well when I use the root shell. I can't access the internet from the user shell unfortunately (if I need to, I will figure out how to set up wlan in the shell).
As a root I have added a new user via useradd method and set a password. The problem now when I logged remotely via putty using the new user credential I am able to browse the root folders etc. So how to limit the user just to limited folders only such home folder and maybe one or two other folders.
Mac and Windows Vista have such pretty user interfaces with all the transparencies and stuff. Is there anything for Ubuntu Linux to improve the way it looks?
