Hardware / Sometimes Pepeprmint 10 does not detect 2nd monitor (HDMI)

I normally run the Nvidia metapackage from nvidia 440 open source for my display driver.

The problem is intermitent.  Sometimes it will go several days without reoccuring.  Since I must switch between WIn 10, and peppermint 10 and peppermint 9 I reboot this computer often. I would like to be able to fix it without rebooting.  Once it is in the correct mode it seems to work fine.  When it defaults to the single screen mode and I run ARAndR it only shows the single screen and the display defaults to 1024 x 768.  This problem never happens when I boot on Win 10.  This leads me to believe it is a software vice hardware problem. 

Any ideas?  would I be better off using the X.Org X server Noveau display driver?  I am very comfortable using teh terminal, if that helps.

Thanks for any advice

This is targeted at gamers who want to install the Game Store "Steam" on their computer.  I was able to easily install the store, but when I tried to download the game I wanted "Overload", download speeds were very slow (They were less than 1/10 of my network speed.)  After reading various posts in the Steam commiunity forums, I thought maybe I had a problem with an overabundance of DNS queries flooding the local DNS server.

So I started Wireshark, and verified that the IPV6 Queries were being refused several times a second.  On a hunch I turned off IPV6 on the computer.   That resolved the problem. now Steam is downloading the game at or near line speed. 

Turning off IPV6 is pretty straightforward but requires you use the terminal;

Here is the "Script" I used:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1

I put in a text file on my desktop, labled IPV6 Disable and then made it executeable, this is done by:

1.  Right clicking it,
2 Selecting properties, at the bolttom of the menu
3. Select the permissions tab at top
4. At the bottom select allow executing file as program
5.  Save it

When you run it, you will need to enter your password

I also created an IPV6 enable text file to turn IPV6 back on:

Use the same process, except the text in the file is:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0

Hope this helps people trying to download Steam games.

Networking / Cannot start PPTP or VPNC VPN on peppermint 9 (SOLVED)
« on: April 23, 2019, 05:05:37 pm »
About two months ago I Installed VPNC (IPSEC).   Witopia is my VPN service provider.  I have installed VPNC on Peppermint 5 and 6 and still use them with no issues.  When I first installed it on this computer (Peppermint 9) I was able to click the VPN connection and it would connect,   Now when I single click the VPN connection it does nothing.  When I double click the specific VPN connection it opens up its configuration.  I am at a loss as to what to do next.  I need to figure out how to start the VPN connection.  Before I had a menu item "VPN connections" when I selected theNetwork Icon on the start bar.  Now I don't have that menu item.  Do I need to reinstall the network (dameon)?

I bought this from Amazon with the idea of connecting it up to my peppermint laptop.  Here is the Amazon description: “Carantee USB WiFi Adapter 1200Mbps, [2019 Upgrade] Wireless Network WiFi Dongle with 5dBi Antenna for PC/Desktop/Laptop/Mac, Dual Band 2.4G/5G 802.11ac,Support WinXP/7/8/10/vista, Mac10.6-10.13” 

From the terminal  I did a

 sudo apt-get install linux-headers-generic build-essential git

Not sure I really needed to, but I did it.

Copy  the RTL88x2BBU....zipped file from the LINUX folder on the included mini CD  to a folder on your hard drive

Unzip it, it will produce a subdirectory of the same name with a bunch of files in it.

Change to that directory

From the terminal run the make cmd

Wait till it completes:  Then from the terminal run sudo make install

Then run sudo modprobe 88x2bu

I then did an ifconfig and the new adapter is there (wlan1)

Cycle the wireless on and off, and you should see the new adapter


I noticed this when I tried to install NMAP  on Peppermint 9. When I did a sudo apt purge, I get the following errors:  see bold

Software & Applications / IPSEC VPN Installation details for peppermint 9
« on: January 11, 2019, 10:46:29 am »

I use a VPN (witopia) service that details how to setup their VPN service on Ubuntu.  I have used them with earlier versions of peppermint without issue.   For the XFCE desktop they recommend installing the network-manager-vpnc package.  I tried this without success.  As it turns out I needed to install the network-manager-vpnc-gnome package as well.  In earlier versions of peppermint I only needed to install the network-manager-vpnc package.  If you are using a VPN using IPSEC or PPTP, please note this requirement.

Installation / Installing Peppermint 9 on a new SSD (SOLVED)
« on: January 09, 2019, 09:01:20 am »
Hello all,  This may seem like a stupid question.  I bought a new desktop and installed Win 10 on it....Sorry, I need to keep Win 10.  Put a 256 GB SSD in it with the purpose of installing Peppermint on the SSD.  Now the question:  When I go to install peppermint, and choose "something else", and I select the new SSD drive do I need to partition it first, or will the installation do that for me.  If so I can stumble through Gpartd.  If I need to do that what file system do I use?  ext3 and how big should my Swap file be, I have 8 GB of memory.

I should probably know this, but it doesn't hurt to ask.



I have this Asus TP2000s with Win 10 on it.  the small hard drive is full, but it has an SD card slot also.  So I tried installing Peppermint 9 on the SD card.  I partitioned the 32 GB  SD card as ext 4.  installed peppermint on it, and when I rebooted  I got a blank screen with a flashing cursor.   So I rebooted and hit the escape key, and brouht up a bios boot menu.  I booted successfully on windows 10, a good thing.  But when I selected ubuntu, I get a grub prompt  Version 2.02.  with a grub> prompt

I did go into the bios and change the boot order  for windows first.  but if I hit esc I can change which device boots first.  I was asked when I installed peppermint when I wanted the grub menu, and I accepted the default which is on the windows drive. 
I did an ls and got the following response.

(hd0) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)

What command should I use to launch peppermint or can I do this, or do I need to start over?

It Seems to Boot OK, but I would like to get rid of the extraneous file.I also know there is a way to compress the text in this post, so you don't see a bunch of irrelevant data, but I forgot how.  It looks like the GRUB is mis-configured, but I tried to update it with the boot options and it didn't seem to fix it.
Thanks for any help

Hardware / Succesfully Installed Brother HL-2270DW as network printer
« on: December 28, 2016, 06:17:08 pm »

This is for you peppermint users who have a Brother Printer in my case, an HL-2270DW,  and want to be able to use it.  The Brother web site had the software and instructions and it worked. 

Go Here:

Follow the directions as stated, agree with the EULA and press on .  I was successful.

After you download the tool  follow the instructions on the next page:

 Step1. Download the tool.(linux-brprinter-installer-2.1.1-1.gz) (in this case)

The tool will be downloaded into the default "Download" directory.
(The directory location varies depending on your Linux distribution.)
e.g. /home/(LoginName)/Download

Step2. Open a terminal window and go to the directory you downloaded the file to in the last step.

Step3. Enter this command to extract the downloaded file:

Command: gunzip linux-brprinter-installer-*.*.*-*.gz

Step4. Get superuser authorization with the "su" command or "sudo su" command.

Step5. Run the tool:

Command: bash linux-brprinter-installer-*.*.*-* Brother machine name
e.g. bash linux-brprinter-installer-2.1.1-1 MFC-J880DW

Step6. The driver installation will start. Follow the installation screen directions.

 When you see the message "Will you specify the DeviceURI ?",

 For USB Users: Choose N(No)
 For Network Users: Choose Y(Yes) and DeviceURI number.

Fortunately they give you a numbered option, so you don't have to type a 18 character alphanumeric

The install process may take some time. Please wait until it is complete.

When you are done you can print a test page.


Installation / Trying to install PMNT 6 over WIN XP (SOLVED)
« on: May 21, 2016, 10:33:25 am »

I have a desktop I am trying to install PMNT 6 on. It already has Pmnt 3 on it, and works well but I have run into some problems.  It has three disks, A 160 GB Master, that had WIn XP on it.  A 90 GB one with Pmnt 3, and a 500 GB with just data on it.   I used gparted and deleted the NTFS partition off of the 160 GB one, created an ext4 on the  160 GB drive, and created an extended partition for the swap file, but when I try to install Ppmnt 6 on the 160 GB master it says "no root file system is defined"  Please correct this from the partitioning menu.  What am I doing wrong?

Thanks for any help.


Hardware / (SOLVED) White bar at top of Dell 6420 (SOLVED)
« on: March 25, 2016, 10:28:24 pm »
Peppermint 6


I was changing backgrounds on my dell 6420 and now there is a white bar taking up about 1/4" of the screen at the top of the display.  I can't move anything into it, when I maximize an application I can't get it to occupy the space it into it.  Any ideas what to do to get the space back? The dell had an intel video card on it.

The white bar is not there when I come to my login screen, but appears after I log in.

SO what I am saying is my windows do not go clear to the screen border on top.  Did I mee up something in the appearance (Maybe in the Peppermint control center?  This is a dual boot computer and the other OS Linux Mint works fine.



Thank you that fixed it!

New Users / Peppermint6 can't boot up (Solved)
« on: January 22, 2016, 02:31:33 pm »
Hello all!

My install of Peppermint 6 has decided to stop booting up.

After the Peppermint start screen iget a blank screen and the following two lines:
Starting NTP Server                                                          ntpd                                                                    (ok)
Restoring Resolver                                                           state                                                                   (ok)

It then just sets there:

I have tried fixing broken packages from the optional start up menu  (dpkg)) but that has not fixed  this issue

Any Help would be appreciated.  If I can't resolve this, I will need to reinstall Peppermint 6 on it.  I installed it from a USB drive, so if there is a way to restore settings form the USB drive.  I can do that.  I also have MINT installed on the same machine.  So I can see and modify any files on the peppermint partition.

I was unable to fix this directly..SO I just reinstalled peppermint 6 over the top..  I would  like to have fixed it,  just because but had spent several hours and decidec to cut my loses.

Hi all.  This appears to be a problem with Mint as well as Peppermint.

OS = Peppermint 6

WINE = Ver 1.6.2

I have setup an old version of Mathcad to run in Peppermint.  It works well, and doesn't use much CPU resources.  However when I close Mathcad, the CPU use rises significantly.  20% Mathcad, and 10% Wine Server.  They do not close, If we reopen Mathcad, the CPU Usage increases again, maybe 15% more.  When I kill MCAD in Task Manager the usage drops down to 20% Mathcad, and 10% Wine Server.  If I Kill Wine, the Mathcad process closes (Makes sense).

I can manually kill Wine after I am done with the application, but is there a cleaner way to do that?

Worst Case, I was thinking I could write a Script file (As a Windows user I would call it a Batch file) and put it on the desktop.

Not sure how to write that, since the PID changes each time.

Anybody else experience this phenomenon?



I have a windows program I use called Mathcad  The program was originally installed on Windows XP, and is an older version, but works fine  I took the installed WINMCAD directory from the C:/Windows/Programs directory and put it on the Peppermint 6  desktop.  I installed WINE, and when I drill down into the directory and run the MCAD.EXE  file it works fine.  But I would like to make it so it looks more like a native application.  So I put the WINMCAD directory in the ~/.local/share/applications/ directory  I created a desktop configuration file called  Mathcad.desktop  below, and marked it as executable.

[Desktop Entry]
Comment=Windows Mathcad

My goal is to make it so I can just "Click" on the desktop shortcut and make it bring up the program.  As a bonus I would like to add it to the application menu.  I know I am missing something, but am unsure what. 

When I double click the desktop file I get "There was an error in launching the application"

Thanks for any help.
