Ubuntu :: BackingStore Not Working Between Virtual Screens In Kubuntu 10.04?
Dec 30, 2010
I am running Kubuntu 10.04 with KDE 4.2.2. I have a problem with "BackingStore", which does not preserve the contents of a window created by another program (actually PAW, producing a histogram). I have created a small xorg.conf, just containing this code:
Section "Device"
Identifier "VMware SVGA"
Driver "vmware"
Option "BackingStore" "true"
EndSection
The contents of the created window is indeed preserved when putting other widows over it and removing them again. This was not the case without the xorg.conf above. Without this file the content covered by another window is not redrawn after shifting the obscuring window.
However, the content is cleared when I switch to different virtual screen and then coming back to the original one. So Backingstore is not working between virtual windows.
In my old 8.04 installation (with KDE 3) everything was fine with the backingstore: Switching between virtual windows did not clear the contents!

I use multiple screens on my computer in work which is running Ubuntu 10.04 it runs great apart from the VBox VM. I run a windows VM as some apps we use in the office are not compatible with ubuntu and I can't get them running right in wine. In single screen mode I use the VM in 'seamless' mode so the windows start menu just sits on top of the ubuntu panel and I can flip from ubuntu to windows as I please in the same interface (im sure anyone that uses VBox will understand what I mean).
The problem comes when I use a second screen. If I try to run in seamless mode on the main screen it works ok apart from the fact that the windows start menu sits behind the ubuntu panel instead of on top of it. When I move the VM to the second screen I cannot run it in seamless mode at all, if I try the resolution goes hay wire and I only get half the screen (if im lucky). So I just run it in full screen mode which stops me from dragging windows from within the windows VM back to the first screen.
What I want to be able to accomplish is to run the VM in seamless mode on either screen but be able to drag windows accross both screens. Is that at all possible?

OS Linux Mint 10, Intel graphics, SIS usb2vga adaptor.
I have three screens. The netbook screen with the extended desktop onto a vga screen and a third screen connected to a usb2vga adaptor.
The extended desktop screens without the usb2vga adaptor works perfectly. I can maximise applications to either screen perfectly without them spreading across both screens. As soon as I connect the third screen via the usb2vga adaptor maximising an application causes it to spread across both screens yet the third usb2vga screen has it's own virtual desktop environment.
I have tried numerous versions of my xorg.conf file that I have generated to incorporate the usb2vga adaptor to make this work and regardless of what xrandr commands I send including changes to the gconf settings nothing seems to solve the issue.
It seems odd that I can create a panel and position it left, right, top or bottom of the second monitor of the extended desktop and it sticks to the screen dimensions yet I can't get any application to do the same when there is a third screen connected through the usb2vga adaptor.
I don't use Compiz, it crashes my system and I don't want separate workspaces I want the extended desktop with the two separate virtual screens to fit on the two separate screens that form part of the extended desktop.
With Xinerama deprecated what other options do I have.

I have Kubuntu running as a virtual machine, with Ubuntu 10.10 as the host. When I maximize it, it only takes up a small part of the screen. This is really annoying, especially when looking at large programs that are too wide.

I just got Kubuntu 10.10 as a virtual machine with VMware player, with Ubuntu as the host. I've seen some really cool graphics effects with KDE. How can I get these on my virtual machine? Do I need to download a graphic package or something?

I am using Kubuntu 10.04 (+KDS 4) in a virtual machine (64 bit). Kubuntu 10.04 runs fine, but does not have an xorg.conf file anymore where I can set "backingstore true". How do I configure (which system file to edit?) my machine so that backingstore works in absence of an xorg.conf?

get multiple screens working in Xorg with the Intel driver? I can manage to get Dual Head working (one big screen), but I'm interested in having two seperate X sessions (two screens) instead.

I've installed the drivers from nVidia. When I go into the NVIDIA X Server Settings application, in the X Server Display Configuration setcion, and click the "Configure" button, "TwinView" is disabled. Also, clicking "Detect Displays" doesn't pick up my monitor (which is connected through a port replicator - keyboard and mouse in that port replicator work fine).
Has anyone else seen this? Is this just a limitation of the current nvidia linux drivers?

My university uses 802.1x Dynamic WEP, with PEAP, MSCHAPv2, and no CA certificate. Our IT department actually provides instructions for Ubuntu, and they work, but I can't get it to work in Kubuntu. Here's the instructions using the Gnome Network Manager applet:
- Change the LEAP setting to Dynamic WEP (802.1x).
- Change the Authentication setting from TLS to Protected EAP (PEAP).
- Leave the Anonymous Identity option blank.
- Leave the CA certificate setting to None.
- Change the PEAP version to version 0 if running 8.10, or Automatic if running 9.04+.
- Leave the inner authentication setting to MSCHAPv2.
- Enter your username.
- Enter your password.
- Select OK. A warning message will appear about having no certificate; click Ignore.
- Click Connect.
I'm using Kubuntu 10.10. All the same settings are there for the KDE plasma network manager applet, but the connection always fails immediately. How do I go about debugging this? Is there a way to test this out from the command line? (WiFi in general works fine, on regular WEP and WPA secured networks; just having trouble with this one).

I usually use Ubuntu, but installed Xubuntu, Kubuntu and Fedora (xfce). However, none of these three will boot into the desktop! Xubuntu and Fedora-xfce seem to boot, but before it loads the desktop the screen stays black and nothing happends. With Kubuntu, it loads the login screen but every time I try to log in the screen goes black, then it returns to the login screen again. It will just keep doing this until you reboot or shutdown.
I cant see any type of error messages come up and my current install of Ubuntu (11.04) seems unaffected.Does anybody know what is happening here? is it a common bug/problem or something no one has really heard of before? Im just really stumped and cant seem to get anywhere with it,

I installed kubuntu over ubuntu (both 9.10) this morning. in the past have had problems with suspending my laptop on ubuntu, so i tried on my new kubuntu. it entered suspension, but when i came back, all i saw was the login screen and the mouse. But nothing worked. It was just frozen. So i did a forced shutdown (held the power button down till it cut off). When i started it up again, there was no audio, no startup jingle. I restarted about 3 times.Here is the output of lspci:

I'm building a new system, and yesterday I tried to install kubuntu, but could only get it running using the nolapic option (noapic is not nescessary, and noapic without nolapic won't work). Now I have the system installed but can only get it running using nolapic and therefore without SMP (which is a no go for most people, including me).
When I try to boot without nolapic, the system goes just fine through loading the kernel and kubuntu (that is, until the end of kubuntu's loading screen), but when it's done with loading it displays the login screen and freezes completely. No input or activity whatsoever. Sysrq keys seem not to work either.
I've searched for similar problems but had little luck so far. I'm using a ga-p55m-ud2 mobo, core i3 530 (2 cores with HT) and an HD5770 (if this is relevant at all). I was hoping some of you experienced users could suggest some kind of workaround to the problem (maybe the kernel is configuring the lapics towards a lockup?) or instruct me as to how could I know what the system was doing right before stopping, in order to locate more specifically what's the problem.
I've never used linux as my main operating system (trying to migrate to it now), but I have some notion of it, even though I don't quite know how everything works, so I might not be familiar with some commands or parts of the system operation.

I've just completed switching both my laptop and desktop from Ubuntu 10.04 to Kubuntu 10.04, all seems to be working well, except that I can't get my Virgin Mobile HUAWEI E160E wireless broadband modem working. I used to have it working flawlessly in Ubuntu, I've used the smae step as described in this post: [URL] that worked for me with Ubuntu, but the Wireless Broadband tab is greyed out under the manage connections dialog. I'm running the 64-bit version of Kubuntu BTW.

Until 10.10 the NetworkManager applet/widget has not been able to:
- edit the default "auto eth0" network profile
- create/edit system wide network profiles (wired, wireless, mobile broadband)
The networkmanager itself can do it, of course, since long. The GNOME/XFCE counterpart also used to work flawlessly since long.

i am running backtrack 4 (using kde 3.5.10) on my laptop with an ATI mobility radeon HD 4650 graphics card. i installed the proprietary drivers from the ati site, just as i always do in any linux installation. then i installed xgl, and all of the compiz packages, including compiz-kde, but for some reason, my system won't enable xgl rendering. every time i run either "compiz --replace" or "fusion-icon" in the terminal, i lose the borders of my windows, and every thing i've tried so far does not work.

Yet another Linux newbie with wireless problems I'm afraid. I saw some postings that appear very similar but I don't have any Linux experience and don'h to make uncontrolled changes to the environment without expert advice.Background: I have an old laptop (HP Pavilion dv9000) with Vista installed and a troubled history (overheating motherboard failure), so I put it on the shelf and replaced it with a new Windows 7 laptop (Dell Studio 1555). But I have been intrigued by the Ubuntu reviews and thought I would dig out the old laptop and install Kubuntu 11.04 (replacing the 2 Vista partitions with a single Kubuntu partition).
Kubuntu installation was easy and I am impressed by the Kubuntu interface, but I soon noticed that it was not detecting my wireless router, which works fine for everything else (Dell, Sony Bravia TV and also an internet radio). The wired connection is okay (using it now) so I guessed the problem was Kubuntu notognising the Broadcom BCM4311.The network interface tool shows the wired connection but the Wireless tab is greyed out.I also installed Wicd Network Manager but that just confirmed what I knew.I noticed other threads have asked for the lspci and lsusb details so here they are:

XP Pro SP3
Ubuntu 9.10
Kubuntu 9.10
Tri-booting. They were installed in the order I listed above. I ran into a few bugs with Kubuntu, so I no longer want to use it. I want to use GParted on a LiveCD to format Kubuntu and expand my Ubuntu home partition to sit on top of Kubuntu's space right now. If I nuke Kubuntu, will Grub still exist with my Ubuntu/XP entries to boot?

Usually I get a login prompt on Ctrl+Alt+F[1-6], but now I just see a blinking cursor in all of them, along with some boot messages in the first virtual terminal.
Code:
fsck from util-linux-ng 2.6
init: bootchart main process (462) terminated with status 2
init: bootchart post-stop process (474) terminated with status 127
/dev/sda2: clean, (integer)/(integer) files, (integer)/(integer) blocks
init: ureadahead-other main process (870) terminated with status 4
What's even weirder about this is that I uninstalled bootchart a few months ago. Whether that's related or not is beyond me, but the virtual terminals did stop working somewhere around that time. I solved this by reverting to my original /etc/network/interfaces file. Without the loopback "lo" device, the runlevel was never set, and virtual terminals never loaded.
This should be somewhere in the interfaces file:
Code:
auto lo
iface lo inet loopback

Whenever I boot my machine into runlevel 5 (X support) I can't get to any of the virtual terminals. If I do a ps and grep for mingetty I see terminals 4-6 are running. But ctrl-alt-f{4-6} just put me to a blank screen. If I hit alt-f1 I get back to X. I've found that if I start tty2 by running "sudo mingetting tty2" I get the following error in /var/log/messages: mingetty: tty2: no controlling tty: Operation not permitted. I am not using selinux and have noticed that /etc/inittab no longer has the ttys. The reading I have done thus far says it's started by gdm but I don't really see a lot of info about controlling them. Any ideas on this?

Clean install of 10.04 Server 32 bit.Only services OpenSSH Server and Print Server.Machine boots and can be accessed through ssh.Virtual terminals (cntl-alt-1,2,3,4,... do not result in video to the monitor (no sync) or a display.If I type blind, I can log in, ssh back to my other machine, and create a file. So the virtual terminal is there and listening to the keyboard and running, just not creating a display.
This machine has been working fine with 08.10 for quite time up until yesterday, so I don't believe it is a hardware problem.Any ideas why the video on the virtual terminals would not work?

I would like to apply KDE on my Kubuntu because the current one blew up. But each time I to sudo get-apt it seems to be fetching from the cloud. Is there a way I can make it to read from my local Kubuntu CD? I have both Ubuntu 10.04 LTS and Kubuntu Live CDs.
I believe the local disk read should be faster to translate than to bite the bytes across thousands of miles over the wire right?
