• Updated Intel display driver causing errors when booting

  - by cdysthe

  I upgraded to to Graphics Installer 1.0.6 on my Ubuntu 14.04 and installed the drivers using the Intel Graphics Installer. The laptop is Intel Ivybridge powered with Intel HD graphics. It Optimus but I have disabled the Nvidia card in bios. The Intel Graphics Installer installs the package i915-3.15-3.13-dkms.deb which I assume is the updated driver. It causes a bunch of error messages when I boot. Here are the relevant errors from dmesg when I boot: [ 7.206151] drm: module verification failed: signature and/or required key missing - tainting kernel [ 7.208045] drm: module has bad taint, not creating trace events [ 7.336470] fb: conflicting fb hw usage inteldrmfb vs VESA VGA - removing generic driver [ 7.393854] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013) [ 7.393855] [drm] Driver supports precise vblank timestamp query.

• How to reset display settings in XFCE \ Ubuntu 12.04 and also flgrx drivers

  - by Agent24

  I recently upgraded to Ubuntu 12.04 and since I hate unity I installed the Xubuntu package and am using XFCE instead. Since I have a Radeon HD5770 I also installed the fglrx drivers. This all went fine (aside from the fact that the post-release update fglrx drivers have an error on installation and Ubuntu thinks they're not installed when they actually are. I configured my display settings (dual monitors, a 17" CRT on VGA and a 17" LCD on DVI) in the amdcccle program and everything was perfect. THEN, 2 days ago, I accidentally clicked on the "Display" settings in XFCE "settings" manager. After that, everything got screwed. Now, I normally run the CRT at 1152x854 and the LCD at 1280x1024 with the CRT as my primary monitor (with panel) and the LCD without panels etc just to display other windows when I want to drag them over there. The problem is now that if I set my CRT to 1152x864, it stays at 1280x1024 virtually and half the stuff falls off the screen. It also puts the LCD at 1280x1024 BUT then overlays the CRT's display ontop with different wallpaper in an L shape down the right-hand and bottom edges. In short, nothing makes sense and everything is FUBAR. I tried uninstalling fglrx through synaptic, and renaming xorg.conf and also the xfce XML file that has monitor settings but it still won't make sense. Unity on the other hand can currently set everything normally so the problem appears to be only with XFCE. In any case, I can't even get the fglrx drivers back, when I re-installed them, I can't run amdccle anymore as it says the driver isn't installed!! Can someone help me reset my XFCE settings so the monitors aren't screwed with some incorrect virtual desktop size and also so I can get fglrx drivers back and working? I really don't want to have to format and reinstall and go through all the hassle but it looks like I may have to :(

• How do I nstall MS Office 2010 via WINE?

  - by Emeris

  I am trying to install MS Office 2010 on Ubuntu 12.04 on my new MacBook Pro (15"). I already read and followed every existing threads on forums and followed every existing tutorial, but my problem seem unique so far, since whichever solution I try, the problem remains. When I launch PlayOnLinux, two boxes appear one after the other (before the latest upgrade of Ubuntu of last week, the second box did not appear, only the first one did); the first one tells me: Error: PlayOnLinux is unable to find 32-bits OpenGL libraries. You might encounter problem with your games." When I close this window, a second one pops up, stating: Error: PlayOnLinux cannot find 7z. You should install it to use PlayOnLinux. Of course, I tried purging PlayOnLinux (uninstalling it and re-installing it). I also tried other versions of PlayOnLinux. Nothing matters: the problem remains. I did not succeed so far to install 32-bits OpenGL libraries, since I have a Radeon graphics card (which seems to be unusual) and I just cannot find these libraries. Once the two "error" boxes are closed, PlayOnLinux is open, but does not seem to work properly; when I try to install Microsoft Office 2010, nothing happens. When I try to close PlayOnLinux, it is even worse: Unity seems unable to close it (I even had a frozen screen when trying to xkill it through the terminal). I am looking forward to any tips that could help. P.S.: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Whistler [AMD Radeon HD 6600M Series]

• Strange Ubuntu Random Display [Video]

  - by d4v1dv00

  I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself. Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again. My wild guess is, should this be related to driver? Below are my detail system information: $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation H67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01) is there any other information i need to post and how do i do that?

• Is there a way to disable the hardware on/off switch for the Wireless interface?

  - by avee

  I have an HP 520 and is running the latest Ubuntu 11.10. The hardware works fine with Ubuntu with one exception: The device has a hardware switch for turning the wifi on and off. Every time the wi-fi is disabled through the hardware switch, I am unable to bring it on again. The message on the networking popup would be device not ready. What I am looking for is a way to disable the hardware switch altogether so that when users accidentally press the button, the wifi would not be disabled. There is no setting to disable the switch in the BIOS.

• How do I get a rt2800usb wireless device working?

  - by Jii

  My brand new desktop running 13.04 has endless problems with wireless. Dozens of others are flooding forums with reports of the same problems. It worked fine for a few days, then there were a few days where it started having problems sometimes and working sometimes. Now it never works at all. I have 5+ devices all able to connect without any trouble at all, including iPhone, Android phone, 3DS, multiple game consoles, a laptop running windows 7, and even a second desktop machine running Ubuntu 12.04 sitting right behind the 13.04 machine. All other devices have full wireless bars displayed (strong signals). At any moment, one of the following is happening, and it changes randomly: Trying to connect forever, but never establishing a connection. Wireless icon constantly animating. Finds no wireless networks at all. (There are 12+ in range according to other devices.) Will not try to connect to the network. If I use the icon to connect, it will display "Disconnected" within a few seconds. Will continuously ask for the network password. Typing it in correctly does not help. Wireless is working fine. This happens sometimes. It can work for days at a time, or only 10 mins at a time. Various things that usually do nothing but sometimes fix the problem: Reboot. This has the best chance of helping, but it usually takes 5+ times. Disable/re-enable Wi-Fi using the wireless icon. Disable/re-enable Networking using the wireless icon. Use the icon to try and connect to a network (if found). Use the icon to open Edit Connections and delete my connection info, causing it to be recreated (once it's actually found again). Various things that seem to make no difference: Changing between using Linux headers in grub at bootup, between 3.10.0, 3.9.0, or 3.8.0. Move the wireless router very close to the desktop. Running sudo rfkill unblock all (I dunno what this is supposed to do.) I've used Ubuntu for 6 years and I've never had a problem with networking. Now I'm spending all my time reading through endless problem reports and trying all the answers. None of them have helped.

Here is the body: #!/bin/sh /sbin/iwconfig wlan0 power off I then rebooted. No change. I tried adding exit 0 to the bottom of the wireless file, and rebooted. No change. Please note that this is a desktop machine. I'm assuming power management is primarily for laptops, but the iwconfig does state that power management is on, so who knows. The recommended router changes I did not do, since the current router settings are (I think) required for some of the older devices I have, and because the current settings work on all my modern devices including Ubuntu 12.04 and Windows 7. I do appreciate the advice though, and I'll look into it when I have time. Anything else to try? Update #2 I booted into Ubuntu 12.04.3 from a dvd, and the same problems exist. I have a separate old desktop machine with 12.04 installed that has no wireless problems at all. So obviously the problem is wireless hardware compatibility in both 12.04.03 LTS and 13.04. Update #3 The same problems exist even when using a wired connection. I plugged an ethernet cable directly to the router and the network manager added an "Auto Ethernet" entry, but it cannot establish a connection to it. So the problem is not specific to wireless. Meanwhile, I purchased a Trendnet N300 wireless USB adapter, TEW-664UB. I plugged it in, but I have no idea how to get Ubuntu to try and use it. Can anyone tell me how? Can I download a package on another computer and copy the .deb over to do an install, etc? I'm installing windows 7 to double check that the internet connection works there and it's not just some magically faulty hardware. Thanks for your help.

• HDMI video output not working for external monitor

  - by user291852

  I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

• Google Chrome not rendering webpages correctly

  - by sumit_gt

  I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem?

• Screen flickering when using midrange brightness values on Dell XPS

  - by Eliran Malka

  After a fresh Ubuntu install on my laptop, I discovered the function keys for screen brightness control (Fn+F4 and Fn+F5) are not working. Digging around here, I managed to get it to work by following the solution suggested on this post and that one, but alas — after applying it, a strange problem occurred: Setting the brightness level to any value other than minimum or maximum, the screen starts flickering back and forth from the selected level to full brightness, apparently due to Dell's power saver attempting to dim the screen to adjust the brightness levels. I looked up for a solution here on the site, and possibly everywhere, with no avail. Also tried: To manually control the brightness by configuring the ACPI level (setting values by echo [some_value] | sudo tee /sys/class/backlight/[vendor]_backlight/[some_key], without success. Installing the Intel graphics driver, thinking it's missing. Realized it's installed out of the box by installing Mesa Utils. How to resolve this?

• usb wifi dongle on ubuntu server, cannot install realtek driver RTL 8188cus

  - by Sandro Dzneladze

  I got cheap Ebay wifi dongle from HongKong, Im trying to set it up on my ubuntu server. Occasionally need to move server, so it cannot always be connected to router via lan. Anyhow, usb wifi came with a driver cd. I uploaded files to my home directory and tried to run install script (RTL 8188cus): sudo bash install.sh But I get error: Authentication requested [root] for make driver: make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/2.6.38-8-server/build M=/home/minime/RTL 8188cus/Linux/driver/rtl8192CU_linux_v2.0.1324.20110126 modules make[1]: Entering directory `/usr/src/linux-headers-2.6.38-8-server' make[1]: *** No rule to make target `8188cus/Linux/driver/rtl8192CU_linux_v2.0.1324.20110126'.

• fglrx: No matching Device section for instance... found how to fix it?

  - by Lejo

  I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa. The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do. It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus? in xorg.cof different bus is indicated: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

• Input signal out of range; Change settings to 1600 x 900

  - by Clayton

  I recently installed Ubuntu 12.04 onto my HP Pavilion, in an attempt to make the desktop able to dual-boot Windows 7 and Ubuntu. I managed to get down to the last step, and finished the installation process. After it prompted me to remove what I used to install Ubuntu, I did so, removing my SanDisk 8GB flash drive, and allowed the system to reboot. Like usual, the desktop booted with the HP image, with the options at the bottom(Boot Menu, System Recovery, etc). However, when it should have started up with Ubuntu(like I'm certain it should have done), I received the following error: Input signal out of range Change settings to 1600 x 900 From the time I installed the operating system, back in late August, till now, I've been trying to figure out how I would go about fixing this issue. My mom is also starting to get frustrated with my not having resolved the issue, as its the only desktop that has a printer installed. Is there any possible way to resolve this? To summarize the problem: -Successful boot -Screen brings up error -Screen goes to standby -Nothing else possible until desktop is rebooted, which will initiate the above three steps A few notes: -I did not back up my computer before I installed Ubuntu. I didn't have anything to write to, and basically just forgot to. : -I don't have a Recovery Disk. -I don't have the Windows 7 disk that is supposed to come with the computer. -It has been narrowed down by a friend on Skype that the problem lies with the display, and that the vga= boot command does have something to do with fixing the problem Thank you in advance for resolving this problem. I greatly appreciate it. ^^

• Dell XPS 15 L502x and Ubuntu 11.04 - HDMI output

  - by Jones

  Recently I've bought my dream's notebook, a Dell XPS 15 but since then this dream became a kind of endless nightmare. I'm almost getting crazy to make my graphic card driver work properly, but it seems to be just impossible. Yes, I have a 2GB NVIDIA GeForce GT 540m (Optimus) in it! It simply doesn't work. Every time I generate the xorg.conf Ubuntu hangs on while starting up, which forces me to remove this file to be able to start the notebook with the standard graphic settings. Another problem is that the Dell XPS 15 does NOT have a VGA output, but a HDMI. So, to be able to use a second monitor I have to configure it by the NVIDIA X Server Settings, which just works if the driver is properly initialized with the xorg.conf. I've also tried to make it work with the Bumblebee, but unfortunately it didn't help me much with the HDMI output. Do you guys have any idea to solve this deadlock? Is there any way for me to use my second monitor?

• Monitor not detected after booting without monitor attached (12.04)

  - by cawkie

  I had a stable 12.04 machine running perfectly. The machine was booted without the monitor connected - since then the system always boots to low graphics mode. Onboard graphics (from lspci): VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) Monitor: AOC e2450Swh Display widget shows monitor as laptop(!?) and system details shows graphics as Gallium 0.4 on llvmpipe (LLVM 0x300) X-server log appears to show correct monitor detected. When I boot from a live CD I get full 3d graphics I've tried the monitor on a different machine - all OK. I've tried a different monitor on this machine - same problem. Between having a working system and a broken one there have been no updates and I have made no configuration changes... EDIT: I have come to the conclusion that the problem is caused by a known issue with lightDM hanging on battery check. I've managed to get 3D graphic working by switching to using GDM - not a solution but acceptable workaround. I would still like to know what is causing the problem and how I managed to get my system into this state!

• Nvidia 740M still not working after Bumblebee installation

  - by Jon

  first of all, I have checked a lot of similar topics, but I still can't get my laptop to use Nvidia 740M. So first things first. I have a laptop Asus X550V(i5-3230, 4gb RAM, Nvidia 740M + Intel HD4000). I installed Ubuntu 13.10 alongside Win8(preinstalled) and both systems are running without problems. However, I have problem with second graphic card(Nvidia 740M), as Ubuntu doesn't recognize it. I installed bumblebee with this tutorial https://wiki.ubuntu.com/Bumblebee#Installation, but I still get error "Cannot access secondary GPU" error when trying to run ''optirun Steam'' in terminal. Then I tried to do this: [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. you need to edit the /etc/bumblebee/xorg.conf.nvidia (or /etc/bumblebee/xorg.conf.nouveau if using the noveau driver) and specify the correct BusID by following the instructions therein. But with lspci / VGA i get only info about Intel 4000, but no Nvidia. When I type only lspci, I get the line for Nvidia 740M,but after I edit the config file I still get second card error. Also, in /etc/bumblebee/xorg.conf.nvidia there wasn't BusID or anything similar, so I just added the whole line in device section. As I sad, I tried a lot of things to get it working, avoiding this forum(as I din't want to bother people with some solutions possible), but alas!, I had to bother you. If there is a need for some additional info, just say, no problem at all. Thank you very much in advance. :)
