[PLUG] boot failure
The precursor may or may not be related. I discovered that my wife's gmail had been accessed by an iphone on Nov, 1. We have no iphone, and were home alone at the time listed.

A power switch intervention was required, but it booted fine at that time. So the two incidents point to hardware problems or intrusion?

I give lots of presentations, using a smaller, older laptop
with HD15 ("VGA" and other resolutions) video. The docking
cradle has DVI, but I prefer not to lug along the extra weight,
so I have a HD15 to DVI and HDMI adapter.
About 10% of venue projectors are old and HD15 only, about 10%
are HDMI only screens, most have more than one interface, some
have all three, and even have ethernet. Most problems stem
from projector and screen aspect ratio, with older systems
using 4:3 and newer systems using 16:10 or 16:9 or some
other media-focused aspect ratio.

Re: [PLUG] VGA still useful?
I'm looking at doing a control system job with Dell rack mount servers
rather than my usual personal computer boxes. I am disappointed to see
that the Dell R430 on-board video is VGA only (I assume HD15).
I had to replace my flat panel lately, and was not surprised to see that
HD15 connectors are going away on new flat panels.
I was able to get one (Acer) with HD15 VGA, DVI and HDMI, but it wasn't
the best buy at Best Buy. But for the time being, I can support older
systems without some sort of an adapter.

Re: [PLUG] boot failure
I want to add something here in case it helps. I had emailed PLUG when I had an issue with my computer as well. It's an old MacBook. I ended up going with this solution after doing some research and experimentation: 1. I created a bootable thumb drive with an Ubuntu on it. 2. I accessed the grub menu by pressing the 'alt/option' key during startup. 3. I selected 'Ubuntu Advanced options'. 4. I pressed 'e' to make edits. But instead of making edits, I pressed 'F2' to get the grub terminal. 5. On the terminal I entered these 3 lines: (1) set root=(hd1), (2) chainloader +1, and (3) boot. By following these steps I was able to reinstall Ubuntu from the thumbdrive. Note: I did not salvage any files with this process. I just wanted to completely wipe all files and reinstall Ubuntu.

Now there is something I can do. CD 12.04 seems to run fine. So you would point to SW. How about the HD? Is there a chance that an intruder mucked things up?

[PLUG] How do I solve an internal error with Ubuntu.
Hi. I have received this error message several times now. Error message: Sorry, Ubuntu 12.04 has experienced an internal error. I got to the point where this message was displayed: http://www.ubuntu.com/support/ is the best place to get free help with technical issues. I was planning on going to that website. I'm not sure what else to do. Does anyone have any suggestions? Some additional information: I used to have Ubuntu 14.04 on the machine. I've had that OS on my old MacBook for about 1 year and it recently started giving me the error above). The error pops up frequently. So I decided to install Ubuntu 12.04 because I originally had that version of Ubuntu on the machine. But I still get the same error with Ubuntu 12.04.

Re: [PLUG] boot failure
Denis, Be sure you ran the system with the CD 12.04 for awhile, and you used the system as you normally use it. If you have a heat problem, you need to exercise your system as much as possible to see if the problem reappears. You can run diagnostics on your hard drive from the CD to see if you have a HD problem. Someone on the list will know more about disk utilities on your CD than I do. If there is no heat issue and no HD issues, then you may have been hacked. Mark On Wed, Nov 4, 2015 at 2:21 PM, Denis Heidtmann wrote: > Now there is something I can do. CD 12.04 seems to run fine.

Re: [PLUG] boot failure
Thanks for the information. I have been running the system on the dvd for a number of hours without incident. I just ran sudo fsck.ext4 -fv /dev/sda1. There were a number of errors, but nothing which looked very serious to me. (All errors corrected.) I should have captured the reports to a file, but instead I took two photos. Errors were inodes part of a corrupted linked list, inode w/zero dtime, block bitmap differences, free blocks count wrong, inode bitmap differences, free inodes count wrong. There were no bad blocks. If the details are important I expect I can get the photos up. I should point out that this HD is new as of August, as is the OS (ubuntu 14.04 replacing 12.04). Assuming I have been hacked, how do I recover? (I have not tried to reboot since running fsck.)

Re: [PLUG] boot failure
The "attempt to read/write outside of 'hd0'" message has me thinking your Grub installation was/is bad. Maybe a fresh "grub2-install" will fix it? I was wondering about the partition table, but if fsck(8) was able to scan/fix the partition(s), then the partition table data is probably OK. The corrupt data in the 'sda1' filesystem isn't good. Do you suspect that power was simply yanked from it at one point? Is there any other reason why the data on your disk might be corrupt?

Re: [PLUG] boot failure
Yes, power off was used to recover from a freeze recently. I noticed in some google responses that BIOS restrictions on HD size could cause this. My upgrade in august was from 500G to 1T. I will have to search to see if this restriction applies to my BIOS (asus version 09907 01/13/09). -Denis On Thu, Nov 5, 2015 at 3:05 AM, Don Buchholz wrote: > > The "attempt to read/write outside of 'hd0'" message > has me thinking your Grub installation was/is bad. > Maybe a fresh "grub2-install" will fix it? > > I was wondering about the partition table, but if fsck(8) > was able to scan/fix the partition(s), then the partition > table data is probably OK.

[PLUG] I'm trying to get sound through my headphones.
Hi everyone. I recently installed Ubuntu 12.04 on an old MacBook. Everything seems fine except I can't get sound through my headphones. I can only hear audio through my built-in speakers. Whenever I plug in my headphones, there is no sound and there is a red light that glows from the jack. I've searched for a solution online but so far nothing has worked. This link describes the exact problem but their solution for modifying the file /etc/modprobe.d/alsa-base.conf did not work for me: http://www.upubuntu.com/2012/04/headphones-not-working-no-sound-under.html. This other link also describes a solution by modifying the alsamixer. However, I do not see a headphone jack listed in the alsamixer. Does anyone have any suggestion(s) for me? Do you think that upgrading to a newer version of Ubuntu would fix the problem? ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

If all is well the Headphone control will show up and you can maneuver to it, hit m for mute/unmute, increase it's volume and it will be working. I have to do this every time I reboot.
