PostPosted: Tue 22 Jan 2019, 21:37    Post subject: remove USB stick after boot  

is there a way to remove the USB stick after boot, run from RAM layer, then reinsert the USB stick before shutdown and save the RAM layer onto the USB stick? i seem to bump the USB stick into everything as it protrudes 2 inches out of the side of my laptop.

i tried currently, but when i re-insert the USB stick it mounts with a different name so it cannot backup properly when i shutdown.

I think such an option would add a lot of value to fatdog since laptops are ubiquitous nowadays and i assume others may be as clumsy as I am when moving around.

A couple of things to consider. 1. Use a nano usb stick as they only protrude about one centimetre. 2. Use the blkid to identify your usb stick rather than sdb1 etc. This way your usb stick will always be found. Look in Fatdog help for boot options for more information. Search for uuid.

I don't believe that qmake is in devX. I need it to build synergy.

Edit: I installed "qt5" from gsplat and it had the missing file Smile

Edit 2 I also installed qt4 since I couldn't figure out how to compile synergy for qt5. My previously complied package for synergy worked after installing qt4.

Modifying fstab seems to prevent fatdog64 from stating up. This seems to affect the current and previous version of fatdog64. Here is an example line I added (ip and mount point slightly modified):
Code:

//192.168.x.x/puppyshare /mnt/samba     iocharset=utf8,file_mode=0777,dir_mode=0777,uid=0,gid=0,credentials=/etc/samba/smbcred 0 0


This modification of fstab works for me to access a samba share from another computer. Unfortunately it prevents me from booting.

The fstab line you posted is missing the required file system field, cifs in this case.
How does Fatdog64 "not start", can you describe in more detail? Does it hang at some point in the boot process? What's on the screen at that point?
How do you connect to the network? wifi or wired, when you mount the samba share successfully after Fatdog64 has booted?
If Fatdog64 hangs while booting you could try to add option "showerr" (without quotes) to your initrd line in the boot manager configuration file or directly from the boot manager menu. This option directs boot error messages to the screen.
One of the things that could block initrd is password prompts from the samba mounter. With "showerr" you'll be able to see such prompts. I see that you've included a credentials file to the samba mount options but maybe it isn't enough.

PostPosted: Tue 29 Jan 2019, 16:45    Post subject: Usb scanner CanoScan N656U  

I have a usb scanner CanoScan N656U that worked with xsane on Fatdog 721.
However, in Fatdog 800b it is not recognized in xsane.
In both cases running without savefile.
The results of the sane-find-scanner and scanimage commands are
In 721:
Code:

# sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

found USB scanner (vendor=0x04a9 [Canon], product=0x2206 [CanoScan], chip=LM9832/3) at libusb:002:004
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.


# scanimage -L
device `v4l:/dev/video0' is a Noname HP Webcam-101: HP Webcam-101 virtual device
device `plustek:libusb:002:004' is a Canon CanoScan N650U/N656U flatbed scanner

In 800b:
Code:

# sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

In 800b xsane only recognizes the HP Webcam-101: HP Webcam-101.

The sane-backends (this scanner uses plustek) are version 1.0.27 in Fatdog800b and 1.0.25 in Fatdog721

A stab in the dark:
http://sane-project.org/ wrote:
Note 3: The Linux USB3 workaround which was added in version 1.0.25 is now disabled by default. If you have difficulty using a scanner which previously worked, or intermittent scanner availability, try setting the new environment variable SANE_USB_WORKAROUND=1 before starting your frontend.

Greetings!

@SFR
Thanks for your hint. I had already tried it and it was not solved either.
Found the solution at https://wiki.archlinux.org/index.php/SANE_%28%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87%29#For_plustek_scanners
Some plustek scanners (noticeably Canoscan ones), require a lock directory. Make sure that /var/lock/sane directory exists ...

In Fatdog721 that directory exists, but in Fatdog800b is missing.
Creating this directory in Fatdog800b with the same permissions that it have in Fatdog721, the scanner is detected and works correctly.

The owner and group of /home/spot in the devx sfs is set to root:root , which causes problems when the devx loads over the basesfs (for example, seamonkey-spot does not start).

Similarly /home/default and /home /ftp in initrd?

Thanks. This is a bug, we'll fix it.

This should not be an issue because initrd is always at the bottom of the stack, but I'll make sure that the basesfs overrides these two as well.

@h2sammo: use the "multisession" mode. Multisession mode does not "hog" your device, you can take it out and plug it back in later.

PostPosted: Thu 31 Jan 2019, 22:40    Post subject: 50% CPU Usage when idle  

Apologies for the late report. As p310don mentioned back in December in this thread, I am seeing unusual CPU usage. I am running kernel v4.19.10.

It happens about 15 seconds after reaching desktop - CPU usage increases to 50% and remains there. HTOP shows nothing.

Additionally, I have a problem with wine:
Code:
# winecfg
wine: created the configuration directory '/root/.wine'

EDIT: CPU Usage returned normal after around 10-15 mins. Unsure if it was something I did.

EDIT2: /etc/init.d/91-autochownd was the cause.

@jake29: which version of wine?

autochown ... Do you have a lot of stuff under "Downloads" folder? If you do, it could explain it.
