• Cannot boot after installing ubuntu on lenovo x120e

  - by tutysara

  I have installed ubuntu 11.10 on my x120e using amd64 alternate iso image. The installation went fine, but it is having issues while booting after a successful installation, it says - "No Operating System Found". I followed the instruction at - help.ubuntu.com/community/X120e#Installation to purge grub-efi and installed grub-pc, even then I couldn't boot into ubuntu.(got the same "No Operating System Found") This is the file from boot-repair with this setup - http://pastebin.ubuntu.com/926556/ Then I asked in #ubuntu and they suggested me to create a bios-boot partition, I was not very comfortable with the solution they had suggested but gave it a try anyhow. I re-sized my initial partition and made 4 MB free space in the beginning of the partition and had set the flag bios_grub. Re-installed ubuntu 11.10 this time using amd64 desktop iso image file. Installation went fine as before but finally this time also the system didn't boot, it gave the same - "No Operating System Found" message. In BIOS I have the settings as to use both (Legacy and UEFI) and with UEFI tried first. This is the boot-repair file from my latest setup - http://pastebin.ubuntu.com/926761 Any help/suggestions are appreciated.

• Key binding in Compiz no longer works

  - by Dave M G

  I have a key binding set in CompizConfig settings manager that runs this command: sleep .5 && xset -display :0.0 dpms force off I have it attached to Super+~. It's worked fine for years. Now, suddenly, it stopped working. When I open CompizConfig the key binding is blank. I set it again, close CompizConfig, and it doesn't work. So I open CompizConfig again, and the key binding is blank again. It won't save what I set it to. How do I get my key binding and command to work, and stay working.

• Newer versions of chromium?

  - by user128712

  I've been wondering why the ubuntu's version of chromium is still on 25 -- from lucid up until raring -- while the current stable version is 28. The only reason I use chromium is to use the web apps integration. PS : I have tried to use the web apps integration on another version of chromium -- not google chrome -- which is 28 then it seems that some features I use was lost while using other version than 25. EDIT: Sorry I forgot to tell you I use the 13.04 version and also the development branch 13.10. My question was : Why does ubuntu doesn't update the package in the repository to the current stable version?

• Grub problem - Command prompt

  - by RhZ

  Update: Thanks to all who helped. I gave up and am going to re-install. Not the end of the world, no files will be lost :-) This time will be backing up grub haha. Thanks again, I really appreciate the community's help on this. I was going along fine when the new pae kernel came down, and it had some bug where the sound was all messed up. So I used startup manager to choose the older pae kernel and rebooted. But startupmanager must have fuXXored my grub. When I re-booted, I get thrown directly into memtest and thats it. I tried to re-install grub using the live disc method that I found in many places. That changed something so I get a prompt and the message: "GNU grub version 1.99 ubuntu. Minimal BASH-like editing is supported. Type help for complete list." But then I tried the live CD fix again and now am back at the memtest... What can I do to get my system running again? UPDATE: Just to be clear,when I start up I get a blinking cursor in the top left, and the word 'ON' in the middle of the screen. Then, after a good minute or two, the memtest starts.

• ubuntu 10.04: boot error for custom compiled kernel - gave up wating for root device

  - by atharva

  Hi, I have installed lucid on my Lenevo Laptop (Y 410 series , x86 platoform) and it is working fine. Now I have compiled kernel 2.6.37 from the downloaded from the kernel tree. I followed usual procedure of compileing kernel (make menuconfig,make. make modules etc). Then I created the initrd image using mkinitramfs and updated my grub using upadate grub command. Update-grub detects the initrd image of the compiled kernel. However when I boot from this kernel it gives me following error: Gave up waiting for root device. Common problems: -Boot args (cat /proc/cmdline) -Check rootdelay= (did the system wait long enough?) -Check root= (did the system wait for the right device?) -Missing modules (cat /proc/modules; ls /dev) ALERT! root=UUID=/... does not exist and then it falls onto initramfs prompt. I have tried following solutions discussed in different ubuntu forums: 1. disable uuid and point root=/dev/sda8 (sda8 is where my kernele image resides (both default kernel and compiled one) from /etc/default/grub 2. compile kernel using CONFIG_DEVTMPFS=y suggested here Still I am unable to boot from the compile kernel. Could someone please suggest me the solution ?

• Double launchers and mouse captured between screens in Twinview configuration

  - by Numpty

  Just upgraded to 12.04 and noticed an extremely annoying issue. While using twinview, there now appears to be a launcher on each screen. Moving the mouse between monitors and over the launcher "captures" the mouse for half a second or so, creating the perception of lag. According to some bug reports I've read it appears that a launcher on every screen is a new "feature". Is there any way I can get rid of the 2nd launcher? It's driving my crazy.

• How to get numpad out of "mouse emulation" mode?

  - by Jonik

  My numeric keypad has somehow got into a "mouse emulation" mode where the number keys just move the mouse pointer around (2 = down; 8 = up, 6 = right, etc). Anyone know how to make it work normally again? None of the other numpad keys work either (I first noticed the whole thing when Ctrl + ÷ (numpad division sign) no longer produced "line comment" in IntelliJ IDEA). Toggling num lock doesn't affect this (though the indicator LED works as usual). I'm using GNOME on Lucid Lynx (10.4).

• Cannot get ATI Drivers installed

  - by bittoast67

  I am trying to install the Catalyst driver. The best I can get is a strange resolution problem and firefox acts all wonkt. The worst I have gotten is low graphics mode in which I just reinstall Ubuntu. I have a HP Pavilion Dv7 laptop. With Radeon 3200 HD. I plan to try again with a fresh install of Ubuntu 12.4.3 as I have heard its the most compatible. This is what I have done: I have tried just the easy way of going to synaptic and installing the drivers that way. the fglrx package (not the fglrx update). And if memory serves I think that boots me into low graphics mode. So, fresh install of Ubuntu and tried again. I have done everything a couple times from this site (http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide) following every instruction to a T. That gets me something, such as a lowered fan speed and a much cooler computer, but I also lose most of my resolution. And displays says its the best resolution I can get. I also have a very screwy firefox. Using this method I can see AMD Catalyst Control Center in my dash (two of them really one administrator and one not) but when I try to open it it says no amd driver detected. So again, ubuntu reinstall. I have tried the GUI method from the Legacy driver I got from AMD's site. It runs through smoothly and at the very end after I exit the installer it gives me an error. I have also tried various other methods using terminal, as well as various different drivers (the one from the amd's site and the one suggested in the above link for my graphics card) both to no avail. When I try the method in the link on number 2, and I get the super low res and screwy fire fox. I type in, fglrxinfo ,and get a badrequest error. I have yet to type in fglrxinfo and get anything like what I am supposed to. UPDATE: I am now currently reinstalling Ubuntu 12.4. I tried the above mentioned link - thank you very much!- just to see on the previously failed driver attempt by following the purge commands. And to no avail when typing fglrxinfo I still get the badrequest thing. I will update again after a try with a true fresh install. Thanks again!! UPDATE: Alright everyone. Still no go. I have done everything word per word in the provided tutorial. I have rebooted my computer again to a fucked up resolution and this is what I get when typing fglrxinfo: $ fglrxinfo X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12 I would like to add that when installing this file: fglrx_8.970-0ubuntu1_amd64.deb I got this: Building initial module for 3.8.0-29-generic Error! Bad return status for module build on kernel: 3.8.0-29-generic (x86_64) Consult /var/lib/dkms/fglrx/8.970/build/make.log for more information. update-initramfs: deferring update (trigger activated) Processing triggers for ureadahead ...

• cpu temperature imrpoves very fast

  - by myildirim

  Last few days i found out that when i click google chrome and the open it my laptop starts being angry.That's fans are working hardly and i can not touch the mousepad because of heating.I use Ubuntu 11.10 on my Toshiba A350-22z laptop and monitor cpu and harddrive temperature.Both cores reached 104 Celcius and i read somewhere "if your processor reaches 105Celcius it harms itself".I cleaned inside of laptop a year ago but there is a point : until wheather becomes about 20Celcius there was no problem.I know hardware cleaning is the best solution but how can i solve with another way ? I think problem is about outside's hot wheather.Is there anybody that has the same problem.In addition to Google Chrome i realized that when i open online video the processor temperature increas very fast.

• ubuntu 12.10 Lenovo b570e, WiFi connected but not working

  - by koogee

  I'm running ubuntu 12.10 liveUSB on a lenovo b570e. It has an atheros wifi card that connects with my home network but I can't browse AT ALL. My network is multiple clients --> router --> isp modem --> Internet I can ping my router (192.168.0.1) but not my isp's modem(192.168.15.1). I have 3 other computers connected to the same router that are working fine (infact i'm posting from one) ping -c 3 google.com unknown host google.com ping -c 3 8.8.8.8 shows 100% packet loss I think its some networking issue. I tried directly connecting it to the router via ethernet cable but same issue. It gets an ip, shows LAN connected but can't browse. If I connect it directly to the isp modem via ethernet cable it starts working fine. Connection Information shows: Interface: 802.11 wifi (wlan0) driver: ath9k security: wpa/wpa2 speed: 150mb/s ip: 192.168.0.106 broadcast: 192.168.0.255 subnet:255.255.255.0 default route: 192.168.0.1 primary dns: 192.168.15.1 i have restarted the router and modem many times. Rebooted the LiveUSB many times.

• Just installed 13.10 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.10 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• How can I Fix the CD/DVD refresh for the media drive so that Ubuntu 10.10 recognize it automatically?

  - by Denja

  Hello Community, I have recently installed Ubuntu 10.10 and it seems to work flawlessly. But today I tried to check some CDs and I was surprised that Ubuntu doesn't automatically refresh the CD/DVDs inserted in my media drive. I had to eject manually the CD/DVD from Ubuntu and then Insert the new CD and only then Ubuntu reads the data in the newly inserted CD/DVD. How can I fix the CD/DVD refresh for the media drive so that Ubuntu 10.10 recognize it automatically?

• How to login after modifying ~/.profile wrongly

  - by Jasper Loy

  I did something very silly a few weeks ago. I wanted to add a path so that the OS could find some manually installed executable. Instead of typing 'PATH=xxx:$PATH;export PATH' at the end of the ~/.profile file where xxx is the directory in which the executable lies, I accidentally typed 'PATH=xxx;export PATH'. After I logged out I was unable to login anymore as I probably messed up the whole PATH variable and reinstalled the whole thing. My question is: is there a way of rectifying the situation if I happen to add the path wrongly (hopefully not!) in future?

• Ubuntu 12.04 installation freezes at "Detecting File Systems"

  - by user67970

  I am installing Ubuntu 12.04 onto my system, which I am dual booting an already installed version of Windows 7 with. The installation goes fine until what I suppose is near the end of the entire thing, where it is at the page where it scrolls through the features of Ubuntu. At this point, it is saying: Detecting file systems... It will not go past this point, and it has been at this part for an hour and a half. What should I do to fix this? I am new to working with Linux operating systems, so please help!

• Trying to re-install ubuntu 11.10on an HP Pavillion G6, screen goes black after the ubuntu logo shows.How do I get it to install normally?

  - by Josh Towers

  Installed Ubuntu 11.1 successfully without my wireless device being recognized. Used sudo apt-get update + upgrade commands to attempt to fix this. Computer crashes after upgrade and now it won't finish re-installing Ubuntu, after it shows the first purple screen with the Ubuntu logo, the screen goes black. Used the Derik's Boot Nuke CD and then attempted re-installment again, and the black screen problem remains consistent, seemingly no matter what I do. It sounds like it's installing but won't let me see anything or go anywhere. heelllppp

• Can't login to Ubuntu One

  - by Gabriel

  I uninstalled Ubuntu One about two months ago and now I re-installed it. I can still login with my account through the site (Ubuntu One) but the client keeps telling me "The authentication failed". If I try to use the Recover password option it also fails with telling me that my email address is not recognized (while I can use it with zero issues through the site) If I attempt to create a new account from the client, it also fails to load the captcha every time. Something is clearly broken here but I can't figure out what it is. Any ideas?

• Using an iPad or Nexus 7 as an Ubuntu Second Monitor

  - by never4getthis

  Is there any way to use an iPad mini or a Nexus 7 as a second monitor through a cable? I dont want something like vnc, I need it to work through the usb cable (or any other cable). I imagine that the iPad will get a lot of hate around here, the reason why I am considering it is because of the larger screen (compared to the nexus 7). I think its self explanatory that I need this to work with ubuntu (as I am posting in this formum). Thanks for reading this highly unorganized, typo-flled (<--see what I did there?), un-cohesive post. Any help will be appreciated!

• Ubuntu 14.04 stalling. Problem with LightDM. Plymouth (and logging out) switches over to a black screen w/ white cursor

  - by Kage

  if its a duplicate, sorry. Couldn't find anything that fits my issue, much less that was on 14.04. I changed a few things recently. Switched to the Numix theme (from PPA), installed lm-sensors and psensor (ran all the I/O probes), Ubuntu Tweak, Pinta, and well, Team Fortress 2 on Steam. :P The system will get to the Plymouth 'ubuntu' screen, load load, all dots filled, switches over to LightDM, but wait! No LightDM. :I Just a blank screen with that white cursor. Can't switch out to tty1-6 - not sure if the Ctrl-Alt-F1 is disabled in 14.04 or if its literally just locked down. If I change any files, I have access to the filesystem from my Windows 8 partition. That's it. :/ I'm pretty familiar with Linux, especially Ubuntu, but I think I'm still at the point I know just enough to break things and not always how to fix 'em. Any help would be greatly appreciated. Thanks! UPDATE I was just able to get into my desktop briefly. I booted Ubuntu. When the black screen froze, I hit Ctrl-Alt-Del. When it started switching off, I hit Ctrl-Alt-Backspace. It rebooted. I plugged the second monitor in I had been using before the issue ever came about. Plymouth displayed on both. LightDM came up, displayed on both (it used to show only the ubuntu logo on the unfocused monitor though). I logged in just fine. Even ran some pending software updates. I logged out of the desktop though, and LightDM refused to show again. xP

• Is it Possible to Repair Boot Record on Windows Vista Partition on Dual Boot Ubuntu 12.04.02 LTS Install?

  - by PasBonRJB

  I recently successfully installed Ubuntu 12.04.02 Desktop as a "side-by-side" on an eMachines ET1641-02w PC; which before had Windows Vista; but was no longer bootable, because the boot sector somehow got trashed. After I installed Ubuntu I can go to Devices/OS and I can access all of my docs, pics, videos, music, etc. on the Windows Vista partition; but I still can't "boot" the Windows partition. I've seen several posts regarding recovering boot sectors using the Boot-repair app; but am wondering if this "boot-repair" is only for the Ubuntu partition. Can I use "boot-repair" to repair the Windows Vista boot sector?

• UbuntuGNOME 13.10 - Problem: Keyboard layout: Control L and Caps Lock swapped

  - by linuxubuntu

  I have a problem in UbuntuGNOME 13.10 which I didn't had in prior releases: I did a clean install and I don't know if it was already there or if I may have changed something, but my "Control L" and "Caps Lock" keys are swapped. How to swap them back? See also the attached image. http://i.imgur.com/PR1YB4T.jpg I swapped them back using but this is obviously not a proper fix $ cd ~ $ xmodmap -pke > .Xmodmap $ echo "remove Lock = Caps_Lock remove Control = Control_L keysym Control_L = Caps_Lock keysym Caps_Lock = Control_L add Lock = Caps_Lock add Control = Control_L" >> .Xmodmap $ xmodmap .Xmodmap but the "Keyboard Layout Chart" program shows the keys still swapped. What's the reason for this? How to fix?

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.
