Recently, after booting the window appears "System Problem Detected" - and I choose "Report problem". So how can I find out what actually is the problem? Otherwise everything works as expected. Xubuntu 18.04 on HP15 laptop.

This started to happen immediately after I had rebooted the first time after doing a system upgrade. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved.  I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem.  Here's a screenshot!

I installed Windows on my computer, followed by an installation of Ubuntu. However, now I'm unable to boot into my Windows install.  What can I do to fix this?

On bootup, filesystem check occurs and it stops at 61% and I am redirected to a page with the message you are in the emergency mode. I don't know what to do next.  This is the message that I get at the screen   You are in emergency mode. After logging in, type .......  Press Enter for maintenance (Or press ctrl+D to continue):   But when I press Ctrl+D it again directs me back to the same screen.

Okay, I apologize if there are similar threads... but I've scoured the internet and never have I run across a helpful answer. So I'll ask here...   I have an old laptop, an Acer Aspire 5515... It was running Vista and was taking 5-10 seconds to just do anything, even as simple as opening a folder. So I decided to install a windows-user-friendly version of Linux - something I've wanted to try for a long time. I ended up settling on Kubuntu because I read somewhere that it's medium-light weight, and good for people used to running windows, after all, I can always replace it with something different later on.   I went to the ubuntu site itself and downloaded  "kubuntu-16.04.1-desktop-am64"  Then the problems started flowing in. Some of it user error I admit... first the CD I got wasn't big enough, then I forgot you can't copy past an iso file, then I couldn't get the Acer to boot from cd drive  Eventually, I fixed these... I burnt the iso image right, used a larger DVD, and changed the bios to boot from the cd. I went to try to just 'try' Kubuntu but that just wasn't working very well, so I just went and tried to go ahead and replace the OS. I knew it would kill everything on the Vista, but I already transferred the files I wanted to keep and the computer was unusable as it was, so I figured why not.   I went through with trying to do the installation, and the first time got to about 80% when I got the Errno 5 Input/Output Error  Alright then... it said something about heat so I placed the computer on a low running box fan as a make shift computer fan (It was getting hot anyway), and I tried again. Made it to about the mid-60s and got the same error.   This time, I went and I double checked the iso... it's indeed the most recent one on the Ubuntu site, and then I used winMd5sum, which says the checksum is correct. I then got another disk and downloaded imgBurn and burnt a new disk at the lowest possible speed (tried for 1x, but it did 2x).   Tried again and it still pulled the same error around the same spot.  So this time at the bootup screen I pressed shift and chose Check for Defects, it returned with Errors found in 1 file  The memtest86 says no errors.  So I'm assuming that means there's a problem with the CD/iso? The check sum was supposedly correct and it was burnt on the lowest possible burn with trusted software. Also, the cd drive works just fine and the disk itself is brand new without a scuff on it.  I'm pretty stumped what to do. I'm going to try to find a cheap flash drive at the dollar store or something to try to boot from USB, but if there is any troubleshooting I could do to get this to work without having to spend money I can't really afford, that'd be really helpful.   As it stands I have a nearly 10-year-old computer with no OS whatsoever on it because the windows section is all deleted, but the Ubuntu section is not fully installed.

Initially, the computer was showing the error as mentioned in   question. Fixing it resulted in the above error.  Please take look at the last line   Started GNOME display manager... and deal with any system changes..p link was shut down.....     One more thing before all this problem I have edited xorg.conf file to use  as suggested on .  I don't know if that's the reason but I thought it is important to share.

Since some system updates, my machine can no longer boot properly. I am no Ubuntu guru. I do not have a week to spare diagnosing the issue. I just want to retrieve important data from this machine's hard drive and get a working computer again ASAP.  What should I do?

I am not sure what is causing this problem occurs every time at the start after booting.  Bug reported

Repeated error  I have been repeatedly encountering the following error when my laptop freezes. It may occur multiple times during the day, and should take several minutes to recover.  Source Windows  Summary Hardware error  Date ‎11/‎1/‎2018 10:11 AM  Status Not reported  Description A problem with your hardware caused Windows to stop working correctly.  Problem signature Problem Event Name: LiveKernelEvent Code:   144 Parameter 1:    3003 Parameter 2:    ffffad8c0b1a75c8 Parameter 3:    40010002 Parameter 4:    0 OS version: 10_0_17134 Service Pack:   0_0 Product:    256_1 OS Version: 10.0.17134.2.0.0.256.48 Locale ID:  1033   More details  Per my best reflection, the hardware error occurs when I am using the laptop on its docking station. Here is what I observe:   While using the laptop as normal, the "freeze" will occur and I can hardly operate the laptop: mouse cursor won't move continuously and Alt+Tab won't be able to switch across two windows. Shortly after (usually several minutes), things will go back to normal. Upon inspecting through the Performance tab in Task Manager, there had been no spike in anything, be it CPU, Memory or Disk. When I open the View reliability history tool, I will find another entry of Windows Hardware Error   Machine specification:   Thinkpad T480, i7-8650U (newly replaced module thanks to the manufacture)   With the same pair of docking stations, an older unit of T480 has had exactly the same problem.  Docking station: . Same issue has occurred on two identical docks with  slightly different monitors and accessories. OS specification: OS build 17134.376. Most recent collection of "reliability report":    Possible solutions   First, I would like to learn what exactly went wrong, hardware-wise: the manufacturer's support team did not bother too much with the precise error messages, and have ordered me to reinstall the Windows OS up to 5 times in total. [This is what they called "debugging".]   Please advise if you can decipher the recurrent "Hardware error".   Secondly, I will try to push the manufacturer to replace the docking stations, and see if the same "freezing problem' persists.

I'm brand new to Linux. I just installed Ubuntu as a dual boot system on my HP Pavilion laptop.  Where should I start? I've tried to play around with Terminal over the last hour or so, but I'm probably not helping myself out. Any suggestions are welcome!

I use both Ubuntu and Windows XP. One thing that catches my attention for a long time is the high need for reboots in Windows. Most of the time when I install a program, Windows requests to reboot system. This happens considerably more frequently than Linux.  Why is it so?  Thanks!

Is it possible to disable X at boot time? I'm setting up a server so it would be nice if it wouldn't load the graphical interface every time I boot.

I updated from 18.04 and run Xubuntu specifically. I updated to 19.04 and my wifi works and everything but for some strange reason for a few weeks now, no matter what I do, I cant get rid of this error.  It pops up in the quick black screen that appears before my login prompt shows up.  No matter what I cannot find anything to fix it, my wifi still works but that error appearing drives me up the wall.  iwlwifi 0000:00:0c.0: BIOS contains WGDS but no WRDS   If you want specifics, there's the whole thing from the logs.

I installed Ubuntu and after the installation, i can't boot to XP. When i choose XP from the Grub menu, I got black screen for like 30 sec, and then it returns to the Grub menu.  Thanks!

Along side the question "" that explained the programical aspects of the error and suggested some workarounds, I want to know: what does this error mean?   X is not in the sudoers file.  This incident will be reported.   The former part of the error explains, clearly, the error. But the second part says that "This error will be reported"?! But why? Why the error will be reported and where? To whom? I'm both user and administrator and didn't receive any report :)!

This question is asked often in Ask Ubuntu, sometimes with few hints about the situation.   Please provide a list of possible reasons to help troubleshoot the problem.

I've recently installed Xubuntu 15.04 on my desktop  The video playback was kinda slow and buggy so I installed the nvidia drivers (the gpu is an onboard 7025)  As some people, I get the "ACPI PPC Probe ..." message, but after 20 seconds or so, the system boots just fine, also the video playback is fine and there doesn't seem to be any graphic issues  My question is: Should I be worried about that message popping every time I boot? and what does it exactly means?  I didn't found any answers to that, just workarounds for people who can't pass the message

Error Message:      "A reboot is pending. Please restart before starting Visual Studio".    I installed Visual Studio (Visual Basic 2015 and SQL 2015) and after what looked like a successful install I then got the "Reboot" window.   Not expecting it I had a bunch of things open. So I closed a bunch a bunch of things, and did the reboot myself.   Now I cannot run Visual Basic because it ONLY gives me the above error message in the pop-up window. It won't even let me do a re-install.   All it does is keep giving me the above error message.   If you have any advice that's better than a complete uninstall/reinstall I'm sure everyone in my situation would benefit from it.  How can I resolve this issue?
