When I open my system monitor it looks like this:
Any ideas on how to fix this?
When I type ls in gnome terminal directories show up highlighted in green and the text is blue, making it very hard to read the directories.
I've tried Edit → Preferences and playing around with the color schemes, but the green highlight stays in place.
We are trying to setup the network for an NVidia DGX 1 workstation.
We've connected a network cable that we know works (Tested it on another ubuntu laptop with no WIFI connected).
When we connect it to the DGX1 we don't get an IP address and Firefox just shows the page "Hmm We're having problems finding that site".
Any ideas on how to get the network working?
We've tried this and we don't see eth0 at all
A friend of mine got some PDF files infected with malware. He figured out that if he opens them on Ubuntu and prints them back to a file it removes the malware.
Anyone know if there is a way to script the opening, printing, and closing of a directory of PDF files?
I installed google fonts with Typecatcher, but they are not showing up in Inkscape. Any ideas?
A friend of mine is constantly switching between different laptops that he's working on and he would like to have a Live USB with persistent storage (For Firefox bookmarks, email, etc.) that he can save to the live USB drive so that it all transfers as he's moving between machines.
Is there a way to do this with Ubuntu Startup Disk Creator so that USB drive has a partition that is mounted to a user home directory on startup?
I no longer see the chrome three dot menu. I'm including a screen shot (Hopefully I don't just need new glasses :) ):
Thoughts?
When we are in the terminal and we hit tab to complete the command line, and it can't complete all the way because there are multiple options, the terminal makes a "Bummmmpppp" noise. Is there a way to switch this off?
When we hit the windows key we see all the currently opened applications. Is there a way to see only the windows for one app?
For example I just want to see all the Chrome windows I have opened and filter out everything else.
Anyone know whether ubuntu 17.10/18.04 has a preset keyboard shortcut to to settings?
Update
I think it narrows down to this:
For some reason the host name matters to Nginx when it's trying to figure out whether to proxy the request. If the host name is set to git.example.com the request does not seem to go through, but if it's set to 203.0.113.2 then it goes through. Why does the host name matter?
Filed an issue with Nginx here
Original Question
When I type in the IP address of the reverse proxy directly into my browser bar, it does perform the redirect.
In this case I'll enter 203.0.113.2 and the redirect to 203.0.113.1 is performed.
When using a URL that is resolved via the /etc/hosts entry 203.0.113.2 git.example.com the "Welcome to Ngnix page" is shown instead of the page that would result from the redirect.
IIUC the browser will first resolve the IP address 203.0.113.2 per the URL entry git.example.com, and so both should result in the proxy configuration being invoked, but that is not what happens.
This is the configuration:
server {
listen 80;
server_name git.example.com;
proxy_set_header X-Real-IP $remote_addr; # pass on real client IP
location / {
proxy_pass http://203.0.113.1:3000;
}
}
One interesting thing is that I can navigate to for example:
http://203.0.113.2/issues
If I then change 203.0.113.2 with git.example.com I get Nginxs "404 not found" page.
My Swap space is currently set to 2 GB. How do I increase it?
Also I'm running with an SSD and have 16GB of RAM. What is the Max Memory I can set the swap file to?
The max screen saver delay on Ubuntu 17.10 seems to be 15 minutes. Is there a way to increase to say 45 minutes?
In order to get around an issue with Starbucks WIFI someone suggested spoofing my network cards mac address. How do I detect whether the wifi card supports mac address spoofing?
There is material out there on this, but it is very dated. How do you do this on Ubuntu 17.10?
I ended up just running this:
sudo macchanger --mac 00:11:22:33:44:55 wlan0
Use iwconfig to detect the name of your wireless card. Unfortunately this did not resolve the issue with Starbucks WIFI.
Summary
For some reason Ubuntu loses track of the IP address associated with the router URL that processes the login to the router. I posted an answer that addresses this. Look for the IP address of the router on your phone and put that in /etc/hosts under the name that is attempting to process your router login. That solved it for me. There are other answers as well in case the SB setup is different where you are at.
Details
One post I found on my phone said to add the host IP of the connection service to /etc/hosts. The url displayed in the browser address bar is:
https://sbux-portal.globalreachtech.com/check?cmd=login&mac=a0:88:39:65:f0:cc&essid=Google%20Starbucks&ip=172.31.98.108&apname=24%3Ade%3Ac6%3Ace%3A49%3Af6&apmac=24%3Ade%3Ac6%3Ace%3A49%3Af6&vcname=S17730-VC&switchip=aruba.odyssys.net&url=http%3A%2F%2Fdetectportal.firefox.com%2Fsuccess.txt
So I did that, but the result is the same. Any ideas? Starbucks is the only WIFI I cannot connect to.
Please update us if you know when Google WIFI / Starbucks has fixed this issue.
I tried using a different mac address using macchanger:
Permanent MAC: a0:88:69:15:f0:cc (Intel Corporate)
New MAC: 00:11:22:33:44:55 (CIMSYS Inc)
However that did not work.
Today April 18 I tried a completely different laptop and I'm still getting the same hangup. The message says:
Error resolving "aruba.odyssys.net": Name or service not known.
So so far nothing is working for me. Been on contact with both Starbucks WIFI support and their general customer support and so far no one can provide an estimate on when or if ever this will be fixed. Starbucks support gave me this reference number:
180413-010073
They said to call Wifi support and give the the number and they will fix this. When I did Wifi Support said they don't need the number and there's nothing they can do. For a company that goes out of it's way to provide great customer experiences this is pretty sad. It's been over a month since they rolled this out and still no fix.
When attempting to connect in a browser this is the url it redirects to and hangs https://aruba.odyssys.net/cgi-bin/login.
Update
Also tried using my phone MAC address today. It did not work. The Starbucks Wifi thought I was a new laptop, and so it opened the initial splash page signup again, but after completing the entries it still hangs on https://aruba.odyssys.net/cgi-bin/login.
I somehow rotated the Ubuntu 17.10 screen so it ended up upside down (I think I accidentally triggered a keyboard shortcut). I could not get it to rotate back by clicking the screen rotate button in the task menu, so I had to reboot.
Is there a keyboard shortcut for rotating the screen 180 degrees? The rotation happened on an HP Envy laptop with a touchscreen.
I tried creating an Ubuntu Mate installation on a new SD card today. The Raspberry Pi would not boot (only Red LED lights up) so and I checked the SD card with:
ole:$ sudo fsck -y -b 163840 -B 4096 /dev/mmcblk0p1
fsck from util-linux 2.29
e2fsck 1.43.4 (21-Nov-2017)
fsck.ext2: Bad magic number in super-block while trying to open
/dev/mmcblk0p1
The superblock could not be read or does not describe a valid
ext2/ext3/ext4
filesystem. If the device is valid and it really contains an
ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the
superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
I also tried running e2fsck with alternate superblocks, but it seems they are all bad. However running badblocks did not report any errors.
ole@mki:~/Downloads$ sudo badblocks -o ./badblocks.list -w -s -v -b 4096 -c 16 /dev/mmcblk0p1

Can reformatting the card fix the errors? I tried reinstalling the image onto the card 3 times, but that did not help, so just curious whether it's possible that it's simply a formatting issue?
Update
I reformatted the whole thing using the ubuntu disk utilities, and now it appears to be ok:
ole:$ sudo fsck /dev/mmcblk0p1
fsck from util-linux 2.29
fsck.fat 4.0 (2016-05-06)
/dev/mmcblk0p1: 1 files, 1/1953541 clusters
I'm going to try writing the Ubuntu Mate image again and see if the Raspberry Pi will boot it.
Another Update
Tried burning Ubuntu Mate onto it and after I'm done it the card will not mount in Nautilus and it still will not boot the Raspberry Pi:
ole@$ sudo ddrescue -D --force ubuntu-mate-16.04.2-desktop-armhf-raspberry-pi.img /dev/mmcblk0p1
GNU ddrescue 1.21

I accidentally rsynced .thunderbird to user@host instead of to user@host:/home/user.
Where is .thunderbird now? Is there a good way to search for the folder?
I just installed 17.04 and I'd like to install this: http://www.noobslab.com/2016/11/macbuntu-1610-transformation-pack-for.html
However the repositories don't work. I think there's a simple trick to adjust the repository to allow installation on Zesty instead of xenial. For example after installing the icon repository and attempting an install this happens:
ole@mkiv:~$ sudo apt-get install macbuntu-os-icons-lts-v8
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package macbuntu-os-icons-lts-v8
Any idea how to get around this?
It's somewhat bizarre because on the first attempt it did see all the wireless networks around me. I then put in the password for mine and attempted to complete the install. However it could not connect. I restarted the install, and now it does not attempt to connect to any WIFI network at all. If I boot into live, the enable wifi option in the top launcher is completely gone. Thoughts?
