I just accepted the latest updates for 14.04 and rebooted as instructed and now my computer has gone into super slow motion mode, especially on Firefox. Getting error messages, such as "Keyboard Input failed." Did they just send out the Mother of all Bugs or is there some other explanation?

Hello!

It would be very helpful to know your machine specifications and which point release you are running. 14.04, 14.04.1 or 14.04.2.

Cheers!

Sorry, it is a homebuilt 64-bit AMD computer with 8 gigs of memory. All system details shows me is 14.04 LTS and since I keep it updated I assume I have the latest

Lloydb39; Hello;

Can not help but wonder if it is the 'firmware' package at fault, as there was an update this day:
What version do you have ?


dpkg -l linux-firmware


Mine for reference:


sysop@1404mini:~$ dpkg -l linux-firmware
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
+++-==============-============-============-=================================
ii linux-firmware 1.127.12 all Firmware for Linux kernel drivers
sysop@1404mini:~$

on an old dual core AMD based system.



it's a thought

Looking at the changelog for 1.127.12 (https://launchpad.net/ubuntu/+source/linux-firmware/1.127.12), there was a lot of stuff added (for new hardware) and a lot of patches for existing hardware. So it's quite possible that you have a hardware regression. Try rebooting into an older kernel and see if the behavior changes.

Compare the modules that you are running with the changelog list. As the number increases, your chance of regression increases.

I updated the kernel in two of my Trusty machines this AM to 3.13.0-53-generic and encountered no problems. The only two things I can think of are:

(1) Maybe there is a regression in that kernel that effects your specific hardware so you might try booting the older kernel from the advanced grub menu.

(2) Sometimes kernel updates break proprietary graphics drivers. To see what's up there we'd need some info, like the output of:


lspci -v -s `lspci | awk '/VGA/{print $1}'`

I don't know how to reboot to an earlier kernel or how to get back after I did...

Lloydb39; Wellll ..

Yeah, do check and older kernel:

Grub gives you the option to boot any kernel that is installed, and keeps a list of those kernels:
Boot to the grub menu ( hold shift key as ubuntu boots up ) . -> advanced options and
select a kernel to boot.

Grub will comply.



worth a shot to see what results

Thanks for the help. Turned out to be another AT&T Uverse screwup and not Linux at all. But the tips may be helpful another day.
