80% of the time, when I load my machine up, it freezes after login. Now, we're talking about a fresh install here with barely any additional software.

If I keep restarting my machine, via the onboard button, I can usually get it to start without freezing after 6-10 attempts. Sometimes, it even skips Grub.

What could cause this? I'm fairly new to Linux so wouldn't really know which direction to look with regards to diagnosing these issues.

Not sure if it's a coincidence, but I unplugged my wireless adapter one time and it loaded. The wireless adapter is part of the kernel's automatically installed drivers for the RTL8192CU chipset. I didn't have to install/configure anything with this out of the box.


I can confirm that the freeze appears not to be an issue with my wireless adapter. I just experienced the issue whilst the adapter was unplugged.

What version of Ubuntu and what video card do you have ? – bodhi.zazen Mar 1 '14 at 20:10
I presume is a bug in the wireless adapter, if without it your system loads alright try blacklisting the module. If everything continues fine even after you plug the card again, then report the bug against the kernel. – Braiam Mar 1 '14 at 20:14
I'm using Ubuntu 13.10 with a Radeon HD 7870 Series video card. I had to install Xubuntu with nomodeset checked in order to get it working with my video card – Dan Hanly Mar 1 '14 at 20:15
As a very general advice to start diagnosing your issue, you can hit Alt+F2 while you see that nice splash screen that's displayed when Ubuntu is booting. This will replace the splash screen with a screen that actually tells you what Ubuntu is currently doing. See if your system always freezes when starting a particular service, or if the moment where it freezes varies among boots. Also, since you "only" experience this issue 80% of the time, I would suspect some kind of hardware problem. – Malte Skoruppa Mar 2 '14 at 10:34

Most likely it is the HDD not in place. I had this problem myself. If you have no other choice:

  1. remove the screws on your PC.

  2. lift the keyboard off.

  3. check if your hard disk is in place, or connected properly.

  4. put keyboard back

  5. Put back the screws.

Hope this helps!

It's a fairly new machine (< a year) and the hard drive is an SSD. It's definitely well connected, there's no issues there. FYI it's a desktop so I didn't need to lift the keyboard off ;) – Dan Hanly Mar 1 '14 at 20:22
