• Cannot make NVIDIA driver work with Ubuntu 12.10

  - by user1293231

  I seem to have a problem similar to many but I didn't manage to get it solved: have a Lenovo N581 with an NVIDIA GeForce 610M have just installed a fresh Ubuntu 12.10 64 bits, + KDE and am trying to have my NVIDIA card work. Have tried all workarounds posted: purge nvidia, install kernel source/headers and then reinstall nvidia-current-updates (or just nvidia-current), do "sudo nvidia-xconfig". It does create a xorg.conf but does not much (no Module Section by the way). The result is that my system (jokey) tells me that the driver is there but not in use and I only get a 640x480 resolution. If I try to launch nvidia-settings it does indeed tell me that the nvidia driver is not used. I do all this under kde but I guess it does matter at this stage. Any hint of how to resolve this? I feel stuck and cannot use any of the acceleration which is partly why I got that laptop in the first place... thanks for any help/advise you may provide!

• Ubuntu 11.04 seem's like a laggy OS

  - by user772401

  I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..

• ubuntu 13.10 secondary monitor - doesn't redraw properly

  - by Daniel

  Hi I've just installed Ubuntu 13.10 on a Lenovo w350 and am having some issues with graphics driver. standard nouveau drivers work great on the laptop display but when I attach an external display it goes bad on the external monitor, seems it's not re-drawing properly. (Photo attached). I've tried other drivers but none of them detect the external monitor when connected. Any ideas? 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1000M] (rev a1) screenshot of effected monitor -- http://i.imgur.com/UZWMpQO.jpg UPDATE 1: I have noticed that if I leave the System Monitor open the display improves. Wierd. UPDATE 2: If I leave a video going the lag/flicker issues stop.

• After installing Ubuntu I can't boot Windows 8 anymore

  - by Gian Luca Scoccia

  I just bought a new laptop (a lenovo ideapad Z500) and it came installed with Windows 8. I wanted to have Ubuntu on it too, therefore I resized the Win8 partition from the control panel and installed Ubuntu on the free space I created. Ubuntu works perfectly, Windows does not load anymore... I tried the recommended repair with Boot-Repair but it did not fix, now I get a "Windows boot loader failed to start" on startup and then I get the GRUB screen. The partition summery created by Boot-Repair is here: http://paste.ubuntu.com/1444837/. How can I fix this? Thanks in advance for your help.

• Screen tearing (very noticable during video playback) with HD3000 AND HD Radeon 6630m

  - by NilRecurring

  I did not have this issue with Ubuntu 11.10. Well, to be clear, I did, but it was easily remedied with compiz workarounds. I have tried both the propriety and open source ati drivers, and the intel HD 3000 (as far as I know) should be part of the Kernel already. So I am pretty much 100% stumped given my general lack of Linux knowledge. I really enjoy this OS, would hate to have to return to Windows (read: HATE) because of something as trivial as video playback. Some details: Lenovo Thinkpad Edge e520 Intel HD 3000/AMD HD Radeon 6630m Ubuntu 12.04 64bit.

• Triple monitors on hybrid video system GeForce+Intel

  - by v_mil

  I use Lenovo Ideapad Z580A with hybrid video: GeForce+Intel with Ubuntu 12.10 x64 Ukrainian. It has internal display and two outputs: HDMI and VGA. When I connect third display to VGA all displays go black. Pressing alt+backspace and login causes output to two displays: internal and VGA. System Settings - Displays (or monitors - I have Ukrainian interface) shows three displays: two are on, one (DVI) is off. Turning DVI on and pressing apply causes an error: Can not set configuration of controller CRTC 65. BIOS setting is Optimus (two video cards). Driver for GeForce is Nouveau. With best regards.

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken? Specs: Ubuntu 10.10 Maverick Meerkat IBM/Lenovo Thinkpad R60, ATI Radeon x1400 Mobility all updates installed Linux User 1 year+,

• laptop screen goes blank after waking from sleep

  - by Tojo Chacko

  I have been facing this issue from the last week after some update. Whenever my laptop wakes up from suspend state it just shows me a blank screen. Regardless of whatever I do(move my mouse, press keyboard buttons) it just refuses to wake up. I am forced to do a restart and lose all my unsaved files. Has this issue been reported for Ubuntu 12.04? I am using a Lenovo X200 with Intel Mobile 4 Series Graphics Chipset. Please let me know if any body has found a fix for this.

• Upgraded to Ubuntu 12.04--keyboard & mouse no longer work--system down!

  - by Mackey Morgan

  I upgraded from Ubuntu 11 to 12.04, today, and everything seemed to go smoothly up to, and including the reboot. However, I now find that my mouse and keyboard no longer function, so I cannot login or otherwise use my computer. I have read other posts on this topic, but most of the answers seem to require the use of a keyboard to implement the solution--and I can't use my keyboard! I downloaded a 12.04 LiveCD and tried booting from it, but I have the same issue with that--no keyboard! My systems is a Lenovo with an AMD64 dual processor, and my keyboard and mouse are USB attached and shared with two other Windows PCs via a KVM switch (so I no the keyboard and mouse work!). I would appreciate some hints about how to make this PC usable, again. Thanks!

• 12.04 - sound is laggy when running games through Wine

  - by orzechowskid

  Lenovo U400 Wine 1.5.5 Ubuntu 12.04 with all updates applied I'm experiencing severe (~500ms) audio lag in all games run in Wine. Portal 2, Half-Life, World of Goo, and Fallout are all exhibiting this problem. When I run winecfg though and click the "Test Sound" button at the bottom of the Audio tab, the sound effect appears to play immediately. So I'm not sure what's going on. I don't think it's a problem with PulseAudio by itself since totem videos and Youtube clips both play in perfect sync. Anyone have any ideas on where to start fixing this? thanks! (edit: I thought this was limited to Steam games but I installed a non-Steam game and I now see that's not the case. I get audio lag in other apps too.)

• Cannot connect to wifi after downloading 12.04, repeated prompts for password

  - by Daytown3487

  I have had this OS for a little bit but this is my first upgrade and my first issue I am trying to deal with without my buddy who got my on Ubuntu in the first place (who is on the other side of the country.) I am running an IBM Lenovo T400 Thinkpad that had 11.10 on it and worked flawless. I upgraded to 12.04 a few weeks back and I have not been able to connect to the wifi in my home or anywhere for that matter. I have been trying to mess with it through reading the forums and am not quite sure what my problem is. I am running off of Fios Internet and the wifi keep disconnecting and prompts me to retype the password for reconnecting. If you guys could give me a step by step process of how I should go about fixing this I would GREATLY appreciate it!

• Screen Resolution Problem with Ubuntu 14.04 and VirtualBox

  - by user3341257

  Environment: Lenovo T530 running Windows 7. Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box. Have installed all the updates from both Virtual Box and Ubuntu. Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window. I am seeing only the upper right hand of the screen output of what I would normally see. Please help. I've seen How do I install Guest Additions in a VirtualBox VM? But, none of these answers works in 14.04.

• Resolution problems

  - by tampe125

  i'm having some troubles with screen resolution. First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed. As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help. My natural resolution is 1366x768, but I'm stuck with 1024x768. This is my hardware: lspci | grep VGA 00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) How can I fix that? Is there a ready-to-use driver or I have to compile that from source? At least, is there a solution, at all? :(

  I'm having problems both with bluetooth and wifi, my pc is a Lenovo B5400.

What are the commands I can use to see what's going on? Thank you in advance

• W520 External monitor setup with Ubuntu 12.10

  - by user108372

  I just installed a fresh Ubuntu 12.10 64-Bit Desktop on my Lenovo W520. It looks like there are a lot of challenges around making it work with out of the box Nouveau drivers or propriety Nvidia drivers or Intel GPU. I looked at couple of notes on how to make it work with Bumblebee with Optimus Nvidia. None of them seems to work for 12.10. Anybody has a solid answer on this? It seems like a lot of people are suffering from this. Here is my xrandr output. Let me know if you need any additional information. Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1920x1080 60.0*+ 59.9 50.0 1680x1050 60.0 59.9 1600x1024 60.2 1400x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Thanks, Sef

It went very well, but when i was reboot laptop after installation, it started Win7 not Ubuntu or bootloader for choice. LiveUbuntu is working very well. I tried install ubuntu a couple of times from other .iso. I tried recover Grub. When i change "boot" flag in gparted to partition with Ubuntu, BIOS show me error "missing operating system".("boot" flag is optionally on Windows partition c:/). Can it be hardware mistake? Or i did some mistakes?

• Dualboot - Windows partition does not work [0xc000000e] + video

  - by Chestnutjam

  Some may claim that this has already been asked, but I don't see MY problem in any of those posts. And if they actually have the same problem as mine, I may not understand what they've been trying to point out, actually. I hope you understand as to why I require a direct answer to the problem I'm having. Here's a video: https://www.youtube.com/watch?v=lyu_BsUTk5Q Some information that may help: This is a Lenovo laptop which came with Windows 8. I installed Ubuntu 14.04 along my Windows using a USB stick. It is possible to access my Windows (8.1) files from the folder page. I took off the Windows sticker, so I cannot get a Windows CD or anything from the support guys. I would delete my Windows partition then, but it's also tangled in this geeky mystery. Thank you in advance!

• Wireless mouse temporarily freezes when resume from standby

  - by R Pennese

  I have been getting a very annoying problem since recently in Ubuntu 12.04, probably due to another update that did more bad than good... When I resume from sleep on my Lenovo Thinkpad T420, my wireless laser mouse (Logitech M705) freezes at regular intervals (15.20 seconds) for 5 seconds then works again. This happens regardless if the computer is on battery or on AC power. How do I debug this? I am getting tired of the fact that my system gets more and more unstable over time while it should be the opposite...

• How do I turn off WLAN automatically when LAN is connected?

  - by derroman

  I use my Thinkpad laptop with a docking station. The docking station is connected to my router via LAN. When I walk around the house I use my laptop with WLAN. Is it possible (and how) to manage these devices with a script or something to work like this: If a LAN-Connection is up, the OS should turn off Wifi and if LAN-Connection gets lost (undocking) Wifi should turn on automatically. I use Ubuntu 11.04 64bit with Gnome 2. The system works on an Lenovo ThinkPad R500 with. WLAN-Device: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] LAN-Device: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02) Any help would be appreciated. Thanks.

• Unable to change desktop environment in 12.10

  - by LEOXD

  I upgraded to 12.10 some days ago and now I'm unable to change between the environments. I currently have GNOME 3 (with extensions), KDE and, of course, Unity installed. The computer is a Lenovo G550. In the login screen I can get into the menu where the DEs are listed, but I can't select one. I can't use a test account of mine, which used GNOME 3, because after I logged in X crashes/restarts. Unity works, but I can't switch from the broken GNOME 3 to Unity. What did I broke during the upgrade and how can I fix it?

• What is the easiest and fastest way to display an SDL_Surface in a window with SDL2?

  - by Semmu

  I would like to have an SDL_Surface representing the contents of the window, just like in the old days with SDL1.2. What is the best and fastest way to do it in SDL2? What I found is that I need an SDL_Window, an SDL_Renderer for that window, an SDL_Texture to render, and an SDL_Surface to create a texture from. This seems a bit too much to me, since I just want to display a single image on the screen. Not to mention the impact on the performance. On my machine (Lenovo Y510p laptop) this whole procedure takes 9ms, without any memory allocation, only using pre-allocated variables and totally black SDL_Surface. Is there a way I could speed up things?

• 12.04 boot failure after update

  - by msanderz

  I am using 12.04 and updated using Synaptic Package Manager. Now, however, when I turn on the machine it fails to boot, just a blank screen. If I shut off the machine and start it again and press F12 (on my laptop) to get the boot menu and select the default for HD-0 it boots OK. I had previously used Update Center and had a similar problem, which I corrected by reverting to "Previous" setup. Are there any fixes for this problem or am I unique in this situation. Ubuntu 12.04 Lenovo G575 laptop msanderz Thanks in advance.

  I recently installed Ubuntu on a VirtualBox VM ... it installed just fine (much easier than on VirtualPC). However, I'm unable to get internet access from the guest OS (ie. Ubuntu). Can anyone give me any pointers on how I might enable this? The Host OS is Windows Vista, and the hardware is an IBM Lenovo. Thanks! :-)
