  • Failed to load session "ubuntu"

    - by harsh
    I installed CCSM to enable window previews in Unity. But when I went into extras, there was no 'window preview' option. So I tried experimenting with other options in Compiz and now there are no borders in the dialogue boxes (close, minimize, restore buttons are not there, I had enabled some 'flat....' option in Compiz. Later, I uninstalled Compiz and then reinstalled it. Now it says "Failed to load session Ubuntu" I can't even access through the guest account, I am new to Ubuntu.(please explain in detail). All I have access to is the login screen (it still shows my custom wallpaper). Please help, I don't want to lose my stuff.

  • Redirect packages directed to port 5000 to another port

    - by tdc
    I'm trying to use eboard to connect to the FICS servers (http://www.freechess.org), but it fails because port 5000 is blocked (company firewall). However, I can connect to the server through the telnet port (23): telnet freechess.org 23 (succeeds) telnet freechess.org 5000 (fails) Unfortunately the port number is hardcoded (see here: http://ubuntuforums.org/archive/index.php/t-1613075.html). I'd rather not have to hack the source code as the author of that thread ended up doing. Can I just forward the port on my local machine using iptables? I tried: sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 5000 -j REDIRECT --to-port 23 and sudo iptables -t nat -I OUTPUT --src 0/0 -p tcp --dport 5000 -j REDIRECT --to-ports 23 but these didn't work... Note that: $ sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain POSTROUTING (policy ACCEPT) target prot opt source destination

  • Screen Scaling Problem

    - by Glenbot3000
    I think this is what it's called but I'm not quite sure tbf, aha. Yeah, so I updated packages last night like I do every night, and when I booted my computer this morning I had a problem whereby the display ran over the edge of the screen. This has been a problem for a while, but I rectified it by changing a setting on the nVidia program, however I think it has been updated to remove said feature as I can't find it anymore. I have no settings on my screen to adjust this either, so I'm sorta stuck without the ~20px around the contour of my screen. It is a problem at all available resolutions. Here's a lil' pic of my problem: https://docs.google.com/file/d/0ByPHeBI8W35GcmZYOThWZ0hGd0k/edit Edit: Probably also worth mentioning the screen was originally detected as "Laptop" in the Display setting and had many resolutions to choose from, however now it's displayed as "OEM" and only has three.

  • How to safely back up the "Private" folder?

    - by ImaginaryRobots
    I have an ecryptfs "Private" folder in my home directory, and it is set up to automatically mount whenever I log in. I want to set up automatic backups to a network drive, but I don't want the contents of Private to be readable on the remote server. My understanding is that the Ubuntu "Backup" utility would run while I'm logged in, so it would see the folder contents without encryption. I'm backing up from a laptop, so it is essentially only on when I am logged in. I know that the Private folder is essentially a mounted filesystem, so it seems like I should be able to backup the encrypted image rather than the cleartext contents. What steps are needed to safely back it up, while maintaining the encryption? Note that I'm already familiar with the backup tools available, this question is about dealing with the ecryptfs folder safely.

  • HTTP(S) based file server

    - by Michael
    I've got a server running Ubuntu 10.04. I've already gotten openssh for ssh and sftp on it. I've been looking for a web-based (http, or preferably https) file server, perhaps a web-front-end to an (S)FTP server, that allows access to a specific folder, and also allows uploads. It requires user authentication, preferably using PAM. This web-based solution is for users that are not allowed to use FTP software / browser extension and don't have flash / java browser plugins within their corporate environments. So far I have looked into: Webmin: Includes a file manager, however it uses Java, and I'm looking for a plugin-free implementation. Apache2: I was able to set up https and PAM authentication, but the barebone implementation doesn't include file upload (as far as I'm aware of). HFS: Haven't tried it out because it is for Windows/wine only, and I don't want to run it under wine.

  • Unity on Ubuntu 11.10 - The Dash Home button brings up the panel, but is empty

    The dash home button brings up a panel that is greyed out, but it is totally empty.

Unity seems to reset, but I get the following warning over and over: cs space validation failed unity What should I do next to try and fix this? Edit: Attempted fixes: I've refomatted, did not work. I've done apt-get remove unity then apt-get update then apt-get install unity, did not work. I've switched to Unity 2d and this seems to work. How can I get regualar Unity working or atleast find the error?

  • How do I reset the default icons from the desktop icons?

    - by Jens Reubsaet
    I know this question sounds cryptic, but what I mean is this: I set different icons for the 'home' and mounted volumes on the desktop, but I want to revert that action. How do I do that? I already tried to do it from the icon selection dialog by clicking revert, but no effect. How do I restore this? (the desktop icons are from the default GNOME Icon Theme but I have the Faience icon theme: these do not really match up). Thanks in advance! I'm running Ubuntu-GNOME 13.04 64-bit (GNOME 3.8.2) I set the icons by right clicking, clicking the icon and selecting it by the dialog.

  • How do I left-click a Java Application on a WeTab running Ubuntu 12.10? (workaround defect in Onboard)

    - by Kat Amsterdam
    I installed Ubuntu 12.10 on my weTab. Everything works perfectly (albeit slowly) and I can touch and use every application execpt ones written in Java. When I start any Java Application the touchscreen does not recognize the left click. I believe it's a problem in OnBoard (the onscreen keyboard) because when I touch the mouse icon on the OnBoard and then the Java Application the left click works. This is very cumbersome for every click to first hit OnBoard mouse icon and then button in the Java app I would like to click. It defeats the purpose of a touchscreen. The Java Application is definitly touchable as it's running on 10 other machines with Elo Touchscreen. How do I get Ubuntu to recognize the left click in a java application automatically when I touch the screen? Or a way to dignose this so I can make a clear bug report? This happens in all the desktop environments (Gnome/Unity, XFCE4 and LXDE) I tried with openjdk-6-* and openjdk-7-* Stats: WeTab 32GB 3G 2GB RAM Intel(R) Atom(TM) CPU N450 @ 1.66GHz - 64-bit Ubuntu 12.10 - 64 bit Unity Desktop environment Xubuntu Desktop environment Lubuntu Desktop environment The real touchscreen driver from EETI (eGalaxy) (also didn't work with the Ubuntu standard touchscreen driver)

  • WinXp display driver incorrect to boot iso ubuntu 12.04

    - by user285829
    I have Windows Xp on a HP Pavilion w/AMD Athlon 64 processor 3300+. I have downloaded Ubuntu 12.04 iso desktop. When trying to run Ubuntu, I get a line that says "sis 630 buss not detected. It continues and makes a blue screen, then says low graphics mode only and has a white screen. The HP has display adaptor sis 760, driver= 6.14.10.3671, 4/20/2005. I'm not familiar with ubuntu because I've never got it started as yet. Can the Ubuntu install process be changed to accept my sis 760 driver? I'm trying to make a Live CD(dvd) to run Ubuntu.

  • Dual Frame Buffer on Ubuntu 12.04 Intel HD Graphics 4600 i7-4770

    - by user3692512
    I have 2 monitors connected to the PC, one in HDMI, one in DVI. I have Intel integrated graphics HD4600 Now as far my understanding, both the monitors is connected at the same framebuffer /dev/fb0 How can I detach them and create 2 frame buffers at startup, so that I can directly write to the second monitor, by writing on the /dev/fb1, and not hamper the /dev/fb0, so that x-server can run normally on that?

  • Ubuntu won't start - blank screen with flashing white cursor

    - by loomy
    My laptop is dual-booted with Windows 8 on one partition and Ubuntu 12.04.3 on the other. I've searched for my issue already, but nothing I've found so far has solved the problem. Since last week, when I try to boot Ubuntu from GRUB, I am taken to a purple screen (as usual), but then to a black screen with a blinking white _ cursor. I've tried leaving it, but nothing else happens. When I hold Shift and edit the GRUB entry to change 'quiet slash' to 'text', the back screen instead asks for my login and password. When I put them in, it tells me the date of my last logon, and then waits for further commands. Being very very new to Ubuntu, I have no idea at all what to try out at this point. I tried to launch FailsafeX, but while that was beginning, it said "unable to run server /usr/bin/x" No such file or directory", then shortly after returned to the recovery mode menu. Pressing Ctrl+Alt+Delete goes through an Ubuntu loading screen, then the laptop then restarts. Any suggestions will be very appreciated, and apologies if this is a common issue that has been answered a million times before.

  • Video freezes when larger than a certain size

    - by Poyan
    I have a weird problem playing video files. I have a fairly new (a few years old) graphic card that should and has played up to 1080p video files without much a lot of trouble. I seem to be having a weird issue where the video plays back fine if the window is below a certain size, but as soon as the windowsize increases, the picture freezes. The audio still plays. Usually this is mitigated by killing som applications. Especially GTK (?) apps seem to cause this lag, like having a Nautilus window open usually triggers this error for me. With hardware rendering I get the error regardless of application. I have tried enabling software rendering in VLC and that eliminates the problem (but I get other problems using software rendering, so I've avoided it). I know this is pretty fuzzy, but I'm not sure how to approach this problem. Do you have any idea? EDIT: Some more information. I have the correct and latest drivers installed. My graphics card is a Nvidia 7600 GT.

  • Clicking on active apps on unity launcher stopped working

    - by Tim
    I don't know how it suddenly became this but here's what's happening right now: e.g. I have 2 firefox windows open, so I see 2 small arrows on the left side icon of the unity launcher. Before, when I click on the firefox icon, I see 2 small windows of the firefox so I can choose which one. Now it suddenly stopped working. (super+W still works though). The bug on my system applies to all progams with multiple window instances like nautilus, terminal, etc. Please help, I don't know what to do. I also have cairo dock, compiz, myunity installed in my 12.04. I tried searching online to no avail.

  • Grub errors dual boot Windows 8 / Ubuntu 12.10

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the grub menu, these tow errors show: "can't find command 'drivemap' " and "invalid EFI file path" and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

  • Bit copy of encrypted home and other partitions

    - by Mka
    My laptop is overheating so I need to save all my files before I format the hard drive. I learned how to copy dev/sdX using dd command. However, I am not sure what to copy. Picture from GParted here: http://is.muni.cz/www/256590/fig.png should I copy sda5 and sda6 only? Or sda2 and sda1? I do not need to use these data on another disk, I just want to be able to access them - therefore I want to put them on external hard drive. And last question - how I will then mount my encrypted home? Will it work? Thanks a lot!

  • Theme changes after resuming from suspend

    - by mouche
    I'm using a Dell Inspiron 1520 and Ubuntu 10.10. I've read a lot of questions about graphics problems after resuming from suspend, but most of them are much more serious than mine. I can boot, login and use Ubuntu fine. The problem is that my theme for my top bar and bottom bar changes to gray and blocky (not rounded). Oddly enough, the theme for the title bars of my windows stay the same dark theme. Any ideas how I can fix this? It works fine if I logout and log back in.

  • Cannot view, use, or open CDs or DVDs in Ubuntu 12.04

    - by user67592
    I am fairly new to Ubuntu 12.04 and I have encountered a rather irritating problem. Whenever I insert a CD or DVD (whether it have data, music, movies, or nothing at all), nothing pops up saying "you have inserted a CD", "play with Rhythmbox?" etc. It doesn't show the CD in the launcher/dock or anything of the sort. This is especially peculiar because not only do I have a standard IDE built-in optical drive, but I have an external USB optical drive. Neither work. In addition, whenever I go to "Computer///" and I click (double click, right click, or even left click) on "CD/DVD Drive" nothing happens, when I right click and select "Open" nothing happens either [for either of the two drives (both are listed in Computer///)] And if I insert a blank disk and go to a disk burning program such as Brasero, and try to burn to the drive it detects no CDs or DVDs of any kind. I'm rather stumped and can't seem to find a question similar to this. :( Thanks for all your help in advance!! :) ~Preston Output of sudo lshw *-cdrom description: DVD-RAM writer product: CD/DVDW TS-H652M vendor: TSSTcorp physical id: 0.0.0 bus info: scsi@5:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0414 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-cdrom description: DVD reader product: DVD Writer 300n vendor: HP physical id: 0.0.0 bus info: scsi@4:0.0.0 logical name: /dev/cdrom2 logical name: /dev/cdrw2 logical name: /dev/dvd2 logical name: /dev/sr1 version: 1.25 serial: [ capabilities: removable audio cd-r cd-rw dvd configuration: status=nodisc

  • Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

    - by Izzy
    I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. Helper questions Could it be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? Are there e.g. any configuration files? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current, where I cannot do anything in the application until the window closes. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here) Maybe I should also mention that I'm using the KDE4 desktop (so no Unity or Gnome, though both is installed on the computer). And I did not have this issue before I updated to 12.04.

  • Why won't Remmina connect to Windows 7 Remote Desktop?

Any suggestions?

  • How do I set Ubuntu Bold Font as the window titlebar font?

    - by Ricardo
    I've made a fresh Ubuntu 12.10 install and the Ubuntu Bold font is missing from the font selection screens. This means that if I try to use Ubuntu Tweak to set the title font for windows as "Ubuntu Bold" it does not appear as a choice. The actual file is present in /usr/share. If I use the font in Writer, for example, I can set it to bold without issues. I've tried fc-cache -frv but that's the only thing I can think of.
