Fedora Hardware :: F15 Separate X Sessions Gnome Panel Crashes
Aug 18, 2011
I am starting to get more used to Fedora 15 and GNOME 3, but I still have one outstanding issue remaining. Before explaining the problem, I am using GNOME 3 in Fallback mode because I prefer the look and feel of the gnome-panel over the gnome-shell. Plus, I have performance issues using x11vnc in regular GNOME 3 mode that I do not see in Fallback mode. I cannot use Separate X Sessions (TwinView "0") and get the gnome-panel to launch without crashing. The gnome-panel works fine when I set the screen back to TwinView "1".
Here are the error messages when running from a terminal window:
(gnome-panel:5205): Gtk-CRITICAL **: gtk_style_context_get_background_color: assertion `priv->widget_path != NULL' failed
(gnome-panel:5205): Gtk-CRITICAL **: gtk_style_context_get: assertion `priv->widget_path != NULL' failed
Segmentation fault (core dumped)
Seeing this on two systems that went through F13-F14 upgrade.
version: gnome-applets-2.32.0-1.fc14.x86_64
symptom: via right click on a gnome panel, perform "add to panel" and choose Dwell Click. Gnome panel bites the dust with SIGSEGV at this point, restarts, and then you've got dwell click on the panel.
Anyone else seeing this, and better yet, have a solution?
i've just upgraded from F12 to F14 and my gnome-panel crashes on startup every 2-3 boots. where to look for error messages and stuff so i can resolve the problem, becouse it's really annoying.
My gnome-panel is at the left side of my screen (I use the 'splendid' cairo-dock at the bottom of my screen). But when more than eight windows are open, the dock freezes. The 'Computer' button works, as well as the tray icons. My CPU rushes to 26% constantly. Solution is to kill gnome-panel and it reappears without complaining (if few than 8 windows open).
If I: 1. Add drawer(s) on the gnome panel 2. add items to one or more of those drawers 3. reboot then: 1. all empty drawers can operate normally 2. drawers that have stuff in it cannot be opened.
I want to set up separate X-Sessions for my two monitors. One is an old CRT monitor which I will use as a TV due to it's size/resolution and the first is a laptop panel. First off, I don't have an NVidia card, I am running Intel graphics. Second, I have some general questions. First off would I need a separate desktop environment running on the second screen? How would I switch the focus between the screens? Is there anything else I should know about doing this? This is my lspci readout:

Does any one know how to get the name back on the gnome panel. It seems to have disappeared , I tried using the add to panel feature by right clicking on the panel but cannot locate it in the list.
There are a couple of applications that I want to start at bootup when I load GNOME but not when I'm using KDE. There doesn't seem to be any option for that. Is there any way I can accomplish this?
how to on enable ling separate X sessions with dual monitors in slackware? In rhel all I have to do is enable it under the nvidia-settings... In slackware it does not work that well... to what I understand you have to configure a separate x session...
I've managed to ALT-RIGHT-click-add some launchers to the top gnome-panel. When i now click on a launcher the gnome-panel crashes(?) and reappeares, but the program starts without problems. If i do this two times in a row (1 sec diff or so) the gnome-crash screen appears and i've got to log out although all the programs are still running without any problems.
dmesg shows this: [14460.034820] gnome-panel[4428]: segfault at 18 ip 0000003810fc05df sp 00007fffcaae4c30 error 4 in libgtk-3.so.0.0.10[3810e00000+3fb000]
Is it possible to install Gnome-panel in Xfce? I'd like to completely replace xfce-panel with gnome-panel. It is possible the other way round so maybe this way too?

I tried xfce4-XfApplet-plugin but it doesn't work the way I would like to.
This usb crashes every time copying about 1,200 files of size 800k - 1.2m. Some right away and others randomly. Using the file manager and dragging the image folders from the USB to the local drive. Upon the crash, the USB cannot be used for anything until the system is rebooted.Below are the error messages from GNOME 3 and dmesg GNOME 3 messages:
Error splicing file: Input/output error
A dialog window would ask to Cancel, Skip All or Skip. but by this time the USB had already stopped.
dmseg output:

i have tightVNCserver running to provide me with a means of working on my machine whilst the wife watches mythTV on the (physical) display.
in 8.04 i used to have "gnome-panel &" as a line in my /home/mike/.vnc/xstartup file, and it worked fine, when i logged in via VNC i had a nice gnome panel to start apps from etc.
since 10.04 this stopped working and i had to change gnome-panel to gnome-session. this works... but now it loads everything up in the VNC window just like it does in my main window. this is a problem because it loads things like mythTV front end and so on... i don't want it to do that in my VNC window.
does anyone know how it might be possible for me to have two different 'types' of gnome session? Settings i change in System -> Preferences -> Startup Applications are common to both my VNC and my physical displays so i can't turn off mythTVfrontend in there to solve the problem.
i'm not sure why gnome-panel stopped working in my xstartup file, but it happened when i upgraded from 8.04 to 10.04. if i try it in the ugly xterm window on VNC i get:
Code:
Xlib: extension "RANDR" missing on display ":1.0".
** (gnome-panel:26161): WARNING **: Cannot register the panel shell: cannot connect to the session bus. the RANDR stuff i get when i launch gnome-session too so i think its the second bit that's the real problem.
I have been running Lenny with the non-free nVidia drivers for a while now, but decided to run testing RC2.When I was done my monitor had a solid blue-gray background and the mouse pointer, but none of the GUI parts displayed (blank). After a couple of checks I went back to the gdm logon screen and opened 'sessions' to _not_ find Gnome as one of the choices. So I logged into Gnome(failsafe) and got my full GUI.Console (F1) and xterm also work fine.Trying to get my Gnome Desktop back. GDM is working and I have the session choice for TWM, but with Gnome(failsafe) working I haven't tried it yet to see if it works.
I am using fedora 12 x86_64 gnome. if i turn on panel transparency, whole panel becomes distorted, same thing happens if i choose a panel background.The problem was not there at the time of installation as i once tried it but after updates and all this glitch has appeared. I have experimental ati drivers installed. Is this a recognised bug with panel or drivers.
how to update my GNOME desktop panel? In fact somehow I managed to lose my notification Applet (system tray) because of which I am unable find volume control, network status etc... I hope updating the GNOME can help to resolve my problem on notification area applet. If I can get back the notification area I will be really greatful
This seems like it should be simple to do. I have a fresh F13 install running Gnome, and the gnome panel is on the left-hand side of the monitor. I want it on the righthand side. So far I have been unable to achieve this. I can't drag the panel (even with ALT held down), and if I try to set orientation to "Right" it changes back the "Left" again
So I just updated my IdeaPad to Natty and played around with Unity. The performane was absolutely unbearable so I installed Unity2D from the software center. Now when I start the session everything seems to be fine at first. Whenever I move the mouse over the panel though it seems to switch to my old gnome-panel from the "Classic" session (with some missing icons). When I move the mouse over that panel again it switches back to the Unity panel style. What is going on? Can I fix this somehow? I will have to use the classic session until I get a working consistent behavior
Running Jessie (with a low-pinned Debian-based repositories added to my sources.list (e.g. Kali, kxstudio) for those packages not currently available on Debian (like the Kali menu of security tools). Running on a HP 15-r189nd (Energy Star) laptop.
First question: How do I get GDM3 to add root as an option during login? I can type the root user name in. I don't need it to show the root user in the user list (would actually prefer to need to type it in), but I do want to be able to start an X session as root, since some of the Kali tools (e.g. nmap) needs root to function fully. If I type in root and try to start, it just takes me back to the GDM3 login.
Second question: When I want to select my Desktop Enviroment/Window Manager in GDM3, the list appears below the little gear so I can only see half of the list (xfce not visible to select). How do I change the GDM3 appearance/settings that will change the position of the DE list?
Third question: How do I get multiple X sessions running simultaneously? What I have been able to do, while logged in as myuser and running X on tty7, is to log into a tty[1-6] as root, and then startx -- :1, but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?
Fourth question: When I did the above startx -- :1 as root, it would start the X session in the same tty (e.g. tty2) where I was logged in as root running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work? Or is there something wrong with my setup?
Question 5: Once I have started an LXDE session as root, how do I get it to show the full application menu that my regular user can see? Can I just copy the config files over? Which ones? Or is there a better way?
Question 6: Gnome used to start fine. Then I ran Gnome on Wayland once, and now regular Gnome (on X?) no longer runs, but give me a "Oops! Something went wrong" error and Alt-F4 just takes me back to GDM3. Classic Gnome and Gnome on Wayland still runs OK. Should I log a bug report?
When I get to the login screen on my computer (with ubuntu-desktop, kubuntu-desktop, and xubuntu-desktop installed on Ubuntu), Gnome isn't in the list of desktop environments!
My temporary solution:
I have Openbox/Gnome. I also have an icon in my panel that opens "compiz --replace" so I can still use the regular WM with compiz.
Why my temporary solution isn't good enough:
It's annoying to have to have an extra icon in my panel, and to have to press it at login. Also, I don't get the Compiz splash screen when I login. Overall it's just not as impressive.
Regarding the gnome-panel in Ubuntu (64 bit).... I discovered some time ago that I wasn't the only one who routinely (every login) had their gnome-panel appear butchered, for which Alt-F2 then 'killall gnome-panel' would easily fix.
Having become impatient with this over the past 8 months, I decided I would automate the process and so cofiguring the startup applications seemed like a perfectly logical choice to me. Turns out I was wrong. After adding 'killall gnome-panel' to the startup applications not only does the panel fail to load altogether now, but Alt-F2 doesn't even work.
I tried Ctl-Alt-F1 and working with the graphics-free mode thinking I could somehow navigate to the startup apps config file and edit it, but I don't know where it is or how to edit it without logging in as root and I certainly don't know of any 'root password'.
I've seen this function over in KDE, but can you in Gnome (Fed12 Gnome2.28) let a window sit on top of an non-hidden panel? I've been through the config editior and can't find that choice.
Is it possible to embed the terminal in gnome panel?So I want to listen to mplayer radio / playlist and see on my panel what is now playing?(but the panel is "autohide", soI would like that this "embed terminal" wouldhide with my toppanel automaticly)Simply I want on my toppanel see what is playing in mplayer and how big the buffor is
Anyone have any idea as to what would cause the time in the gnome panel to stop? This is an epic failure... I would have been late to work today if it weren't for the coffee pot. I've had so many issues with gnome's panels I'm considering switching Desktop environments.
Today morning i accidentally deleted the top gnome panel. I created a new one which was just an inch wider. But i am not able to change any of the properties of the panel except position. It says some of the properties are locked down. I have gnome-panel installed already in my system. How do i enable these locked properties.
I created a new panel in Gnome (Fedora 12) and it wasn't showing up right. So I just told it to make another (with the same results), and finally one more. So with the two that are there by default, that's 5 total panels... None of the newly created panels where displaying at all. But after creating the last one the system froze up. Now when I try to boot into fedora my system locks up as it's trying to load GNOME...
Is there any way for me to remove those panels through BASH? So I can just boot to a prompt and get them removed. After that I imagine GNOME will load correctly again...
