I had a problem getting my Epson Perfection V500 Photo scanner working after installing the Epson driver package used in the past. The scanner uses a USB connection. After starting the scan software an informational pop up displayed and told me that I needed to install driver software for my scanner!

I did some searching on the internet and found some pieces and parts that helped me to get my scanner working I listed the sources I used below. They also show some help to get other types of scanners working.

I tested on Peppermint 8 & 9 re-spins. It worked on both. I hope this helps others.

Edit update: this worked on Peppermint 10 re-spin also.

Epson web site:

Ubuntu sane-backends package bug 1728012:
https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012/comments/25

1. I went to the Epson web site and downloaded the .deb Linux driver and the manual for my scanner.
   a) iscan-gt-x770-bundle-1.0.1.x64.deb.tar.gz
   b) iscan_man_e.pdf

2. The install portion of the iscan manual said; in the notes section of the manual that "The SANE package version 1.0.3 or later must be installed before installing Image Scan! for Linux".

3. Use the Synaptic package manager to install "sane". The available version was 1.0.14-11.

4. Now that the sane package is installed we can install the Epson Scanner Software. In the terminal I navigated to the Download directory.

Code: [Select]
$ cd Downloads

5. In the terminal I listed the contents of the Downloads Directory.

Code: [Select]
$ ls

6. The list command showed the compressed file.

   "iscan-gt-x770-bundle-1.0.1.x64.deb.tar.gz"

7. The downloaded file is decompressed with.

Code: [Select]
$ tar xaf iscan-gt-x770-bundle-1.0.1.x64.deb.tar.gz

8. Next list the Downloads directory again to find the uncompressed folder.

Code: [Select]
$ ls

"iscan-gt-x770-bundle-1.0.1.x64.deb" and "iscan-gt-x770-bundle-1.0.1.x64.deb.tar.gz"

9. Change directory to the uncompressed folder.

Code: [Select]
$ cd iscan-gt-x770-bundle-1.0.1.x64.deb

10. Listing the contents of the "iscan-gt-x770-bundle-1.0.1.x64.deb" folder will show.

  "core  data  install.sh  plugins  README.rst"

11. Finally install the Epson Scanner Software by running the install script.

Code: [Select]
$ ./install.sh
It will ask for your sudo password

12. At this point you will see in the menu under the graphics category "Image Scan! for Linux" and "Simple Scan". If you try to use ether app at this point you will get the message "You need to install driver software for your scanner". The following fix will allow the applications to find the scanner driver software.

13. First a symbolic link is created.

Code: [Select]
$ sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane

14. Next we need to create a file in the /etc/udev/rules.d folder and name it 79-udev-epson.rules.

Code: [Select]
$ sudo nano /etc/udev/rules.d/79-udev-epson.rules

15. Add the following text to the file.

Code: [Select]
# chmod device EPSON group
ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0777"

  Ctrl-o then enter to write the file
  Ctrl-x to exit nano

16. reboot Peppermint and the scanner!

17. My scanner worked after following this guide.

Enjoy

User Submitted Tutorials / Peppermint, UnRaid, and NFS
« on: February 11, 2019, 09:58:38 pm »
I spent a lot of time figuring out how to use Network file System (NFS) and thought I would share the bits that work for me.
The reason I started using NFS is I got tired of browsing to my file server using samba. NFS allows you to mount a file server share on your local file system. Note that the ip addresses used need to be fixed. As far as security goes my personal network is never exposed to the outside world. I referenced a lot of sources to put this together and cant say for sure what they all are. Arch wiki, guides found on line, and help files all played a roll. A big help from the UnRaid forum helped me export the shared directory with read write privilages.

https://forums.unraid.net/topic/37310-solvednfs-shares-are-read-only/?tab=comments#comment-358791

1. Set up a NFS share on your file server with read and write privilages. My shared directory is "Box-Backup"

Note: I use an UnRaid server and spent a lot of time geting the share to export properly. I'm not familier with other servers. I can offer some help with UnRaid. The key to getting it working was a rule for the shared directory in the UnRaid server NFS Security Settings.

The rule is "192.168.1.14/24(sec=sys,rw)". This example is using the ip address of the Peppermint install.

2. Next check the the share that the UnRaid server is exporting with the following command. The IP address used for the command is the unraid server IP address.

Code: [Select]
$ showmount -e 192.168.1.10

The command returned.

        Export list for 192.168.1.10:
        /mnt/user/Box-Backup 192.168.1.14/24

3. Use this output to make part of our fstab entry "192.168.1.10:/mnt/user/Box-Backup"

4. Next create a folder to mount the exported share to. My folder is "1-backup".

5. In the Peppermint fstab file we will need to discribe the location that we will mount the exported file to.
   my location or path will be.          "/home/steve/1-backup"

6. Using all the pieces the fstab entry will be the line created below. I will leave the last bits in this entry for you to explore.

Code: [Select]
192.168.1.10:/mnt/user/Box-Backup            /home/steve/1-backup      nfs    defaults   0    0

7. The line above is the entry that needs to be added to the end of the fstab file. I edited the fstab file with nano.

Code: [Select]
$ sudo nano /etc/fstab

8. Reboot and enjoy your mounted server share.

I'm curious about editing the whisker menu in peppermint. I don't want to break anything by removing an application that has dependencies for other applications. But I only want to see what I use. So i figure that i will hide things that I don't want to see. I have played with MenuLibre.

Questions
1. Will menu editing make my desktop unstable.
2. What are other favorite menu editors (why?).
3. Do you bother to edit your menu.
4. Do you ever change categories that your applications live in.
5. Do you leave the menu alone and put your most used applications on a separate panel or dock.

I'm looking forward to some opinions, thanks.

User Submitted Tutorials / nvidia fan control with cool bits
« on: December 27, 2018, 05:49:15 pm »
Hello Peppermint and nvidia users. I'm not a linux expert or programmer. I do like to tinker and linux is a great platform to tinker. Over the last few years I have taken from the community. I thought that I could give back in some small measure by sharing my results of an issue that I resolved with nvidia fan speed control. My gpu fan never seems to turn on. Temps are never what i would consider to be too high but electronics last longer when they are keep cool. I am a lite gamer. The following is what I did to get a continuous fan speed.

I need to give credit to these two sources.
https://wiki.archlinux.org/index.php/NVIDIA/Tips_and_tricks#nvidia-settings
http://us.download.nvidia.com/XFree86/Linux-x86_64/346.59/README/xconfigoptions.html

1. Installed proprietary nvidia gpu drivers.
2. Added nvidia-xconfig file
Code: [Select]
$ sudo nvidia-xconfig
3. Add fan control to nvidia config file.
Code: [Select]
$ sudo nvidia-xconfig --cool-bits=4
4. Add a file called "nvidia-fan-speed.desktop". Create with the following content with a text editor and put in the hidden directory /home/"YourUserName"/.config/autostart/
Code: [Select]
[Desktop Entry]
Exec=nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=30"
Name=nvidia-fan-speed
5. The example above gives a fan speed of 30%. You can change to any percentage.
6. You can check your result if you check the "Thermal Settings" in the "NVIDIA X Server Settings" application.
7. If you prefer command line.
Code: [Select]
$ nvidia-settings
8. There is a warning that cool-bits could cause system damage and void warranties. I'm not overclocking or changing GPU voltages. I'm just applying some cooling. Use at your own risk.

I hope this saves someone some time if you want some control over your GPU fan.

Hardware / nvidia proprietary driver issue [Solved}
« on: July 11, 2018, 10:38:02 pm »
After installing Peppermint 9 I installed the most resent proprietary nvidia driver for my NVIDIA GeForce GTX 1050 Ti. I get one or two good boots into my desktop. At some point when I log into to my account i get to a black screen with a mouse pointer. the session never finishes loading. I can get to a tty session and shut down. I've tried three re installs and my iso passes its checksum. I have no problems with 16 based and 17 based Ubuntu systems. Also no problem with arch based systems. Does any one have any suggestions? Do I need to wait for Peppermint 9 to mature a little. I will miss my pep!

Thank you.
Steve
