I have a problem with unpredictable unresponsiveness of the system while I'm working. I can't isolate a specific cause, as it appears to be completely random, but I'll be working along, open a window or do something like click on a button in a comma-delimited file, or be working in an email, and the next thing I know is that I can't type.


The keyboard is unresponsive. Shift lock and Number lock do not work. The left and right mouse buttons don't work. The mouse cursor moves, but that's the only thing that does. Alt+SysReq+R+E+I+S+U+B does nothing. Ctrl+Shift+F1-F6 does nothing. It's like the USB system is glitching, but it's permanent and NOTHING I do can unstick it or get it to start working again.


I've attempted to connect another USB keyboard (the normal one is a wireless Logitech keyboard and mouse that normally work well) but the second keyboard does nothing. It's like the USB system is shut down.


The ONLY way I can stop this is to hold down the power button and I lose everything. This really is not optimum. But I've seen many posts where heynnema walked through these problems and was able to pinpoint what was wrong, but I've not seen any where the tty console couldn't be conjured up and something done. This is a complete loss of the keyboard and any functionality of the machine.


Any ideas on where to start? Intel Core i7-3770CPU @ 3.4Ghz, 4 cores, 16 GB ram, Nvidia GeForce GTX 550Ti, 1 GB ram; American Megatrends 2014 Bios, Asustek Computer Motherboard P8-Z77-V.

That's all that's there. I think that's a problem, but I have no idea of how to fix it. Will check on the memory slots now.


I verified there are 4 physical memory slots in the motherboard. They are each filled with a 4 GB memory module.


I have pasted the results of cat /var/log/syslog on Ubuntu Pastebin

FWIW, the Patriot Memory modules were in this CPU when I purchased it. If they are the problem, then this is probably why the original owner sold it to me at a very steep discount, and he probably had problems with it.


After following heynnema's directions to remove /etc/openVPN/HMA.conf:


$ sudo rm  /etc/openvpn/HMA.conf

$ cat /etc/openvpn/HMA.conf

cat: /etc/openvpn/HMA.conf: No such file or directory

It is now removed.

You have various problems.


OpenVPN


You have lots of OpenVPN errors in /var/log/syslog. This is due to an invalid VPN .conf file. Delete it:


sudo rm -i /etc/openvpn/HMA.conf

Obtain the correct .conf file from your VPN vendor, ISP, or IT department.


BIOS


ASUS P8Z77-V


You have BIOS version 2104, dated 08/13/2013.


I believe that there's a newer BIOS available, but I can't check for it because there's a problem at the ASUS web site. Call or Chat with ASUS and tell them that you need to check for a new BIOS for a P8Z77-V, but that their support page for that motherboard is broken. See https://www.asus.com/us/Motherboards/P8Z77V/HelpDesk_Download/


Note: The ASUS web page is fixed now, and it confirms that you have the latest BIOS. Apparently you have an "Asia" motherboard, so you may have to check their overseas web pages to check if there's a newer BIOS.


Note: I just checked their tw web page here, and it also shows that you have the current BIOS.


overclocking


Confirm that your motherboard is not overclocked, and that memory XMP is disabled. See your BIOS for these settings.


memory


sudo lshw -C memory shows a couple of problems.


  *-cache:2 DISABLED

       description: L3 cache

       physical id: 7

       slot: L3-Cache

       size: 8MiB

       capacity: 8MiB

       capabilities: internal unified

       configuration: level=3

L3 cache should not be DISABLED.


Also...


  *-memory:0 UNCLAIMED

       physical id: 1

     *-bank UNCLAIMED

          description: DIMM DDR3 Synchronous 1333 MHz (0.8 ns)

          product: PSD34G13332

          vendor: 8502

          physical id: 0

          serial: 00000000

          slot: ChannelA-DIMM0

          size: 4GiB

          width: 64 bits

          clock: 1333MHz (0.8ns)

This should not show as UNCLAIMED.


These might be ASUS motherboard problems... but I'm hoping that a BIOS update will fix these problems.


Go to https://www.memtest86.com/ and download/run their free memtest to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take many hours to complete.


Nvidia


dpkg -l *nvidia* | grep ii shows:

ii  nvidia-settings                    440.82-0ubuntu0.18.04.1    amd64        Tool for configuring the NVIDIA graphics driver

You don't have a server, or a i386. Remove all current Nvidia softwares, obtain the correct Nvidia driver for your Nvidia GeForce GTX 550Ti, and then install it.


sudo apt-get purge *nvidia* # to remove old software
