I'm trying to run pgadmin4 behind an Nginx reverse proxy but I'm having an issue because I need for pgadmin to know it is at myhost.com/pgadmin and not simply at myhost.com.... or at least I think that is the problem.
In other web apps there is usually some setting called webroot or something like that to designate that it should consider itself located there but I can't find anything like that for pgadmin4.
Does this setting exist, if so, where is it?
If not, is there a workaround?
When I right click on an application from the menu I see there is an option "add to Panel" however when I click that it goes to the main/default panel. I want to add icons to a different panel that I added.
I tried adding applications to the main panel and then dragging it to the panel I want it to be in but that didn't work. I tried adding to desktop and then dragging to the panel but that, too, didn't work.
When I open Chrome settings I can look at either 'Settings', 'History', or 'About'. However, if I click on 'Extensions' then that tab immediately closes. This behavior only started within the last couple days and I didn't knowingly install any new extensions.
I looked in ~/.config/google-chrome/Default/Extensions to see if any of the extensions were unrecognizable but the directory names aren't usable; they're just random characters. Here is the output of find . in case that helps.
My problem seemed to start during a manual update although I don't know if that was coincidence or causal. About 20% of the way through downloading the update, it just stopped. I left that window alone for about 20 minutes or so but it wasn't progressing and although it said it was downloading there wasn't network activity.
I xkilled the window and rebooted. During shutdown and then again at boot there was a bunch of these ata1.00: status: { DRDY ERR } entries. When it finally booted into KDE, my graphics resolution had reverted to 768p instead of 1440p and only one monitor came on.
I tried to purge my nvidia and reinstall but I got an error which I forgot but it suggested I run dpkg ... (I forget the ...) which I did. After another reboot, my graphics were still in the same boat and I was still getting the above errors so I googled them and saw that they indicated a problem with my hard drive and weren't directly related to my video driver problems.
I ran mdadm -D /dev/md0 and sure enough it came back saying one of my drives is in removed state, not failure though. The overall state is clean, degraded. At this point I decided to stop screwing around with the video drivers. My question though is, why would the video settings/driver go out at the same time as the SSD (apparently) did if the mdadm is clean? Am I misinterpreting what clean means? Besides making fresh backup of critical data, should I do anything before replacing faulty SSD?
As to replacing the drive here's what I think I need to do.
First manually fail the drive mdadm /dev/md0 -f /dev/sda2
Next remove the drive with mdadm /dev/md0 -r /dev/sda2
At this point I would power down and replace the faulty drive with a new one.
After rebooting I would run gparted on the new drive and then run mdadm --manage /dev/md0 --add /dev/sda2
At this point mdadm would automatically rebuild the array?
Am I missing anything?
For reference here is my latest dmesg
When I boot up my computer and it gets to the logon screen, the display actually spreads across the two of them like I would expect. Once I login it reverts to each monitor cloning the other and the desktop is no longer stretched across both of them. Once I get going I can go into the Nvidia settings and set the displays to stretch again but the settings aren't persistent.
Here's my /etc/X11/xorg.conf

How do I get the settings to persist through logging in?
It looks like this question might be a dupe of this one but that one was closed as too localized for reasons that I can't figure out.
My system is an i7 3820 with 32gb of ram. I do have my system on a 5 disk raid5 mdadm array. My problem is that Google hangouts crashes when I do video streaming (sometimes).
I recently installed Ubuntu server 14.04 with standard Ubuntu desktop. I used to have Kubuntu 14.04. I have since wiped the server version of Ubuntu and reinstalled the desktop version but the problem remains.
When I had Kubuntu my webcam (and google hangouts) worked fine without any special driver tweaking (unfortunately I don't remember which Nvidia driver I was using). Now I have Ubuntu 14.04 and when I try to use Google hangouts with my webcam or screen sharing it crashes after a few minutes. (Just the window crashes, not the whole computer). If I keep the webcam turned off and only use the embedded mic it seems to work fine. Also if I use low quality video it doesn't crash. However, even if it is in low quality, doing a screen share will cause it to crash.
The crashes occur in both Chrome and Firefox. I haven't tried other browsers.
Here's my lsusb -v for the webcam http://pastebin.com/LL6S3wUD although I think the webcam is a red herring at this point, I'll leave this here in case someone wants to look at it.
I have Nvidia Geforce GTX 650 Ti with Nvidia 340.76 driver and then 352.3 and then the 346.82 driver. I was using the 340.76 and then the 352.3 drivers while on the server build and on the desktop build I went straight to 346.82 from the GUI because it's the one that said it was tested.
Here's how the (hangouts) crashes unfold: The first thing that happens is I'll stop getting audio and video of the people I'm chatting with. When I look at my system monitor, one of the CPU cores will go to 100% and the network activity drops to 0. The Xorg process is what seems to be using up the CPU during this time. Xorg won't consistently show a high CPU utilization but the CPU core itself will stay at 100% for a minute or two. After I click through the crash window the processors return to normal usage.
It seems like there's something going on with the window manager but I don't really know what else to try or look at. I started looking at various logs and I came across a couple things, I don't know if they're related. From my dmesg

I googled some of the more dire sounding messages here and most of the links are people who can't get a window manager up at all and/or 5 year old messages that were often solved with new drivers.
My /var/log/gpu-manager.log doesn't have anything that stands out.
Although my /var/log/nvidia-prime-upstart.log just has
Sorry but your hardware configuration is not supported
Here's my /etc/X11/xorg.conf
I noticed I had a bunch of updates come through the other day that required a restart. When I went to restart it just takes me to a user login screen. In the lower right there are options to restart and shutdown. Neither of those buttons work, specifically, clicking on them does nothing. The only thing I can do is log back in.
From there I opened a terminal and did sudo shutdown -h now which returned command not found
I did whereis shutdown and it came back with /etc/shutdown.sh but that shell script just contains shutdown -h now.
It seems my shutdown binary is gone. I did sudo find -name shutdown and it came back with /home/dean/.kde/shutdown but that is a folder not a file.
What should I do?
I'm running Lubuntu 14.10 with a AMD 5350 with Radeon R3 in my living room connected to my TV via HDMI. As long as my TV was on when the system is booted everything is fine (audio and video). However if I turn the TV and leave it off, the next time I turn it on, the bottom half of the display gets distorted. I tried switching to the proprietary ATI driver but that didn't help this problem. The top half is still the correct resolution but just the bottom half is messed up. The only way to get the screen correct again, that my limited knowledge knows, is to reboot the system. I'm assuming the problem has to do with the computer recognizing that there is no connection on the HDMI when the TV is turned off but not readjusting when the TV is turned back on.
Ideally, there'd be a setting to have the computer ignore when the TV is turned off and never change the display as a result of the TV being turned off.
If that can't be achieved, is there a way I can reset the video without restarting the whole system from the command line (or a script)?
