MX-19 RC1 Feedback thread

I had to make another USB. I still get Fatal error Encrypted device /dev/sdb2 is not a LUKS device.
Here is the lsblk output.

Code: Select all

$ sudo lsblk -o name,fstype,label /dev/sdc
NAME   FSTYPE      LABEL
sdc                
├─sdc1 ext4        MX-Live-usb
├─sdc2 crypto_LUKS 
└─sdc3 vfat        MX-UEFI

I don't know if it makes any difference but this laptop is about 2010-2011 vintage and has the old style BIOS.

Let's put the encrypted live USB messages on hold for now. We think we are getting close. For now, encrypted live USB's aren't working.

The encrypt problem stems from the new contradictory defaults in Debian. "cryptsetup luksFormat" defaults to the new luks2 format while "cryptsetup open --type luks" defaults to the old luks1 format. This seems designed to fail. My Gentoo system sanely leaves luksFormat defaulting luks1 so I was not seeing the problem here. Oh well. The usual suspects: anticapitalista, dolphin_oracle, and fehlix provided a tremendous amount of help in tracking this down.

I plan to push modified versions of the live initrd and LUM tonight. I plan to also add a --force=luks2 option in LUM for people who want to experiment with it.

I also plan to write a test checklist so we can catch problems like this earlier. Checklist have improved airplane safety. I hope they will help us too.

1. Lucky Backup as superuser doesn't run after I enter the root password. If I run it in a terminal it says

Code: Select all

jay@mx19:~
$ /usr/bin/luckybackup-pkexec
qt.qpa.screen: QXcbConnection: Could not connect to display 
Could not connect to any X display.

If I edit /usr/bin/luckybackup-pkexec as root and change

Code: Select all

#!/bin/sh
pkexec "/usr/bin/luckybackup" "$@"

to

Code: Select all

#!/bin/sh
mx-pkexec "/usr/bin/luckybackup" "$@"

it launches the GUI app. Just FYI.

Is anyone else unable to run System/luckyBackup (super user) or is it just me?

Same problem with Lucky Backup.
When i edit the Lucky Backup (super user) item properties, at the System category in the Menu and change the command
from

Code: Select all

/usr/bin/luckybackup-pkexec

to the value, as used in MX-18,

Code: Select all

su-to-root -X -c /usr/bin/luckybackup

then it launches the GUI app.

gksu also works. However, if the luckybackup-pkexec shell script is modified on the back end as it were perhaps it can be pushed out as an update which will fix it for everybody, vs. everyone running 19RC1 having to edit their Whisker menus.

Good stuff JayM.

I've asked the package guys to look at modifying the luckybackup package to address this.

Oh, FWIW, on MX 19, su-to-root and gksu will both actually use mx-pkexec.

[JayM]

Thanks, d_o. FYI the Whisker menu command line for lucky as superuser in MX-18 is

Code: Select all

su-to-root -X -c /usr/bin/luckybackup

just to save anyone the trouble of booting into 18 to check.

Ok - just tried in on the thinkpad x 220 - office laptop and the wacom works in krita, gimp, and mypaint. touch sensitive too. should work on the older 201 downstairs. probably no need to try it. worked out of the box as the saying goes!

thanks to everyone. so far everything is really nice and yes elegant in 19!

[Jerry3904]

Nice to hear about the wacom--thanks for the feedback.

[winemaker]

ya i decided to jump in afterall yesterday and do the install on both. need to finish some tweaks and some other stuff - testing. maybe do my wife's soon or leave 18 on there since she has not even tried 18 yet - she doesn't use the dell very often.
