Hi I just got the new Asus N552VX and am trying to get Xubuntu working on it. I have tried both the 14.04 LTS and the 15.14. However in the install I get ACPI PCC probe failed, sometimes it just crashes right there and sometimes it keeps on going but seemingly random freezes up and wont do anything until I restart. I  googled that one and to my knowledge there seems to not one ACPI-driver that fits this particular laptop. I have gotten as far as installing and booting into the OS but the mousepad and keyboard won't work and after a restart it won't boot into xubuntu again. So has anyone else got ubuntu working on the asus N552VX?   Footnote: When it freezes I can't seem to get an error message, I know you can tap the right arrowbutton to see verbose output (of some sort)  but I can't indentify the problem.

All operating systems freeze sometimes, and Ubuntu is no exception. What should I do to regain control when...   just one program stops responding? nothing at all responds to mouse clicks or key presses? the mouse stops moving entirely? I have an    In what order should I try various solutions before deciding to pull the power plug?  What should I do when starting up Ubuntu fails?  Is there a diagnostic procedure I can follow?

I have a Ubuntu machine that I use as a Plex and data server. There is no monitor connected to it. This wasn't a problem with Ubuntu 16.04, but now, with 18.04, it is and it shows a black screen whenever I connect using VNC. I've already created the virtual display using the answer to this question:   Create a 20-intel.conf file: sudo vi /usr/share/X11/xorg.conf.d/20-intel.conf  Add the following configuration information into the file: Section &quot;Device&quot;     Identifier &quot;intelgpu0&quot;     Driver &quot;intel&quot;     Option &quot;VirtualHeads&quot; &quot;2&quot; EndSection  This tells the Intel GPU to create 2 virtual displays. You can change the number of VirtualHeads to your needs.  Then I made a shell script (don't forget to set executable) and put that in Startup Applications: #! /bin/bash /usr/bin/xrandr -d :0 --output VIRTUAL1 --primary --auto /usr/bin/xrandr --newmode &quot;1600x900_60.00&quot; 118.25 1600 1696 1856 2112 900$ /usr/bin/xrandr --addmode VIRTUAL1 &quot;1600x900_60.00&quot;  After this, it still shows a black screen when I connect using VNC. BUT, when I run this with SSH: export DISPLAY=:0 xrandr  After that, I can see my desktop in VNC... Any ideas on how to fix this? Also, when I see my desktop after all this, the dock is missing and all the icons are in the same spot.

I recently installed the proprietary Intel drivers for my Toshiba Satellite A105 s4284 running Ubuntu 14.10. Nouveau was working just fine, I was just attempting to make it so that I was able to run CS:S (no need for explanation on that.)  Long story short, I went and downloaded the Intel Graphic Drivers for Linux* from . After downloading and installing the .deb, I ran intel-linux-graphics-installer which opened up a window that downloaded &amp; installed the open Intel drivers. I then rebooted, and it's slow. Very slow, especially on 3D effects and when I hit Alt+Tab.  Now, I don't know if the previously installed Nouveau drivers are conflicting with these new Intel drivers (if that's the issue, what should I do about fixing it?) What I do know is that my system isn't behaving right and I want it to (obviously.) If removing the Nouveau drivers isn't the solution, how can I safely remove the just-installed Intel drivers?  Does anyone have any suggestions?

I'm using:   Alienware M14xR2 laptop running Ubuntu 14.04 2 * DELL U2412M monitors attached via HDMI and Mini Display Port Optimus graphics (Intel + nVidia GeForce GT 650M) running with nvidea-340 and nvidia-prime, with Prime setup in nvidia-settings GUI to use the NVidia GPU built-in laptop monitor disabled   Unfortunately, the monitors only work successfully in the default mirrored setup - I have the following issues trying to get a dual external screen extended desktop to work:   nvidia-settings GUI can only see one monitor on the X Server Display Config page. System Display GUI can see both displays but can only mirror the displays successfully. By fiddling with Display GUI and ARandR, I temporarily managed to get an extended desktop working, but NVidia GUI still only sees one of the monitors and if I try to reboot with 2 monitors attached, the GUI is totally glitched and unusable after login. During boot, the system just uses the left monitor (via HDMI i/f) for display, so I presume this is treated as the primary display. However, after boot, it appears the system switches to using the Display Port for the primary display and the system will not let me have the Ubuntu launcher only on the left (HDMI) display. The only options that work are for having the launcher on both or just on the right (Display Port) monitor. I tried to forcefully fix the issue with the primary monitor incorrectly being set to the right monitor by changing the primary monitor switch in ~/.config/monitors.xml, however this does not work and causes both monitors to appear at strange resolutions and glitch badly with uncoordinated mouse input.   Running  /usr/lib/nvidia-340/bin/nvidia-xconfig --query-gpu-info gives  Number of GPUs: 1  GPU #0:   Name      : GeForce GT 650M   UUID      : GPU-...

I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that.  Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270.  Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage.  I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not.  Specs:  RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

To switch to Intel GPU from Nvidia 1050Ti, I entered "sudo prime-select intel". Something like: get Intel information showed up on the screen. I logged out and logged in. I went to About but it showed that Nvidia 1050 Ti was still being used. Next, I rebooted the machine. It showed a black screen with a blinking underline cursor on the top left. It stayed there foreover. I pressed the power button continuously. Then, the purple screen with Ubuntu in the middle showed up. After the few dots below Ubuntu turned on, the laptop shut down. I turned on the machine again. Blank purple screen showed up. Then a long list of sentences showed up on the screen quickly. So quick that I could not see what were written on it. Then, again the blinking cursor showed up on the top left. Could you please help to resolve the issue?

When I was installing Ubuntu 11.10 64-bit on my new PC from a flash drive since the only computers I have do not have disk drives, I ran into a problem.  After the ASUS logo when switching on the PC, and pressing F8 to select the USB flash drive, there was the options thing as normal that allows me to select to either boot form the flash drive or install on the HDD, when I do either of these, there is a bunch of text on a black background, as I would expect, but after a few seconds the screen goes blank and the monitor says No signal.  I have previously installed Ubuntu with a flash drive to fix issues caused my Windows and ran into no problems.  Is it a problem with the pen drive I am using? Or maybe a problem with the system? I tried it in my USB 3.0 ports at the back and the USB 2.0 ones as well.  My Specs are:   &nbsp;&nbsp;AMD Phenom II x4 965BE &nbsp;&nbsp;ASUS AMD Radeon HD 6670 &nbsp;&nbsp;ASUS M5-L75 USB3 (typing this from memory, it's an AM3+ ASUS board with USB3.0 in the AMD700 chipet or something) &nbsp;&nbsp;Corsair XMS3 DDR3 4GB(2x2GB) 1333MHz RAM    I ran the memtest program on the flash drive as well, and it came out clean.

So I'm trying to get my laptops NVIDIA fx 880m to pass to a virtual box running window seven on a linux mint 17 install.  So far everything seems to be (maybe) heading in the right direction:  the device passed through happily, when I booted the virtual box it installed a bunch of new drivers, but when I try to install the NVIDIA driver on the guest it can't find the card. I looked under the device manager and there's no listing for the nvidia card under the pci bus, my guess would be that I need to disable it in the host so that it can be passed through to the guest (the virtual box manual said they can't be shared) but I'm not sure how to do so. Can anybody help with this? This question does not seem to me to be a duplicate of , because here the given solution was that it was not possible with a windows host, however in this case the host is linux

I have been having some screen freezing issues on my new Ubuntu 16.04 system, and have been in the troubleshooting process for this issue. I thought it was a graphics driver problem, as I am running an AMD R9 380x card which was supposed to be fully supported by the open-source AMDGPU driver preinstalled with 16.04, but after looking around online, many people seem to have issues with. I thought the answer would be to install the recently released AMDGPU-Pro driver , following the instructions from . However, when I reboot I am getting a black screen. Is there an easy way to revert my changes back? My machine was semi-functional with the freezing issue but now with no video at all is useless to me. How to proceed?

The latest updates (4/1/2018) make my laptop constantly crash the GUI/Unity:  (Intel Pentium su4100 processor)  syslog:  Jan  5 11:38:53 1810 kernel: [ 1850.327738] compiz[11911]: segfault at 0 ip 00007f6c7baf0c16 sp 00007ffd5ec71c60 error 4 in i965_dri.so[7f6c7b513000+82d000]   After login I end up with an empty desktop, just a wallpaper, GUI/Unity are in a crash loop:   No panel.  No dash.  Can't start a program. Launcher disappears. Sidebar disappears. System crash. Windows key not working. The key combination Alt+Tab not working.   Simply, the computer is not usable. Same for guest login. The only thing working: open up a terminal CTRL+ALT+T to examine log files.  I somehow forced  to let me log in and file the bug, but still lots of problems:   Dash not working Alt+Tab not working Sometimes windows all disappear for a few seconds     Any ideas for a solution or workaround?   UPDATE     If you have the same/ very similar problems, follow the link to my    report and mark there that you're affected too. Or file your own. Please leave a comment   if you wish, or upvote - this is a nasty problem - but an answer should   offer a fix or a workaround so users can use their computer again.    Without , Ubuntu can't fix issues.

Background  My Lenovo X250 is arriving in two weeks, which according to  will work well only with "a special image of Ubuntu pre-installed by the manufacturer."   points out that the X250 has "Excellent" compatibility to the Linux OSes they install. On the other hand, a quick search on  or  shows that a standard image of Ubuntu on the X250 is rife with hardware problems.  Ubuntu Certified Hardware acknowledges this for the X250: "Standard images of Ubuntu may not work at all on the system or may not work well." This  clearly shows the difference between an Ubuntu standard image installation and the one that comes pre-installed by the manufacturer. Hardware seems to work fully on the OEM version.  Question  Any idea where we may access or download these "special images of Ubuntu"?  (Hopefully not only for the X250, but also for the other systems out there.)

I have a similar laptop to    But I am opening another question as the problem I face is different. The  and did not find any experience with the Ubuntu installation.  After switching from RAID to AHCI, disabling a secure boot, updating the BIOS, and play around with the BIOS option, I am trying to install Ubuntu 18.04.03.  I am not actually installing it but just using "Try Ubuntu". I pass to the bootloader the options nomodeset intel_idle.max_state=1 without which the installation stops very early. I've also played around with ipv6.disable.  Everything stops while turning on services(see attached figure). In particular acpid.service is the last thing I see, then the system freezes.  I suspect it is related to ACPI setup but don't have any clue on how to fix it. Any suggestion is much appreciated.
