Mouse locator
In Debian I want to locate my mouse pointer. And after searching there are some suggestion using gsettings set org.gnome.settings-daemon.peripherals.mouse locate-pointer false However following that command, it returns No such key “locate-pointer” I install Debian 11 with Gnome initially, though later on I switch to i3 + slim. But gnome related packages are still kept in my env. Any ways I can locate my mouse pointer with e.g. pressing left hand side ctrl key? My environment information: Debian bookworm/sid, Gnome version 40.4. Thanks
gnome-control-center error: Settings schema 'org.gnome.settings-daemon.plugins.power' does not contain a key named 'power-saver-profile-on-low-battery'
My gnome-control-center version is 41.0. I started to test changing some setting in gnome-control-center; however it suddenly crashed and relaunching (by re-executing gnome-control-center command in the terminal) shows the following error. It looks like a key is missing. But how can I add it back or fix this error?

Re: Lock screen with Gnome 3 login greeter
I have gdm3 running. $ ps -ef | grep gdm root 465 1 0 16:57 ? 00:00:00 /usr/sbin/gdm3 I have i3lock installed, but I don't use it. Previously I used xscreensaver, and it worked without a problem. This time I just want to give a test to use gdm style screen lock (so when the screen is locked, the UI is consistent - i.e. UI is presented with the login screen after locked), and it should automatically lock after configuring with e.g. 5 mins goes blank and after 30 seconds delay of going blank the screen should lock automatically. The screen doesn't automatically lock. The screen just goes black after 5 mins (when inactive). Manually locking the screen works without a problem by issuing e.g. i3lock - that would cause the screen goes white with a circle printing `verifying ...` keyword while unlocking. The configuration is in gnome-control-center set the screen to go black after 5 mins. And 30 seconds delay after the screen goes black, as below: # in gnome-control-center Privacy > Screen Lock > Automatic Screen Lock (is configured to turn on with a blue round icon moved to the right hand side of the bar) Privacy > Screen Lock > Automatic Screen Lock Delay (is configured to 30 seconds in drop down menu) My current dm should be gdm3. I check /etc/X11/default-display-manager, it shows gdm3. $ cat /etc/X11/default-display-manager /usr/sbin/gdm3 I understand I can switch to use i3lock, or xscreensaver to lock screen. This time I just want to test whether the screen can be locked (or present me with login screen again after N mins inactive) using gdm3 mechanism, i.e. with login to lock the screen. Sorry I know my intention may look weird. But I found some people seems to get it working https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1896416 And I use the same command, but it doesn't work. So I am merely curious how can I achieve the same effect. Thank you again for your kindly help. Appreciate it!

Re: Lock screen with Gnome 3 login greeter
Ok. The link I found previously is [1]. But executing the command provided in that link doesn't work either. dbus-send --type=method_call \ --dest=org.gnome.ScreenSaver \ /org/gnome/ScreenSaver \ org.gnome.ScreenSaver.Lock I appreciate any suggestions or comments.

Lock screen with Gnome 3 login greeter
I switched to use i3. So now after the screen goes blank, it won't display greeter asking to login again. I read somewhere else on the internet that gdm3 (I use Debian 11 with kernel 5.10.0-8-amd64) no longer uses screensaver to lock the session. Instead it uses dbus to activate login asking user to enter id, password for login. However I don't find any related solutions that work. The closest one is [1] (sorry it's Ubuntu env not Debian). But executing that command (in [1]), dbus-send --type=method_call \ --dest=org.gnome.ScreenSaver \ /org/gnome/ScreenSaver \ org.gnome.ScreenSaver.Lock login screen doesn't come back. So what command should I use so that when the system becomes idle, the login screen will be active? I tried configuring gnome-control-center's Privacy > Screen Lock > Automatic Screen Lock set to on (round icon moved to right). And Automatic Screen Lock Delay is set to 30 seconds. However, it's still active (when becoming idle, screen won't be lock with login display). What steps should I perform in order to lock the screen with login being displayed? I know there is xscreensaver. But this time I want to use login instead of xscreensaver, which is nice of course. Thanks [1]. https://askubuntu.com/a/983451
Re: How to update Debian 11 source.list to testing?
I will change to testing with all keyword switched to testing because my case is more often needing to use newer version software compared to stable, which also works fine w/t a problem for most of time.

How to update Debian 11 source.list to testing?
I just installed Debian using netinstall image. I thought I install testing version, but apparently it's Debian 11. So now my source.list looks like below: deb http://deb.debian.org/debian/ bullseye main non-free contrib deb-src http://deb.debian.org/debian/ bullseye main non-free contrib deb http://security.debian.org/debian-security bullseye-security main contrib non-free deb-src http://security.debian.org/debian-security bullseye-security main contrib non-free deb http://deb.debian.org/debian/ bullseye-updates main contrib non-free deb-src http://deb.debian.org/debian/ bullseye-updates main contrib non-free I want to switch to testing version. In the past I just change the keyword from e.g. bullseye to testing, and generally there is no weird problem. But I read on the internet saying that the source.list should not mix up with different version. For instance, Debian 11 with testing. So I am wondering if there is a better way to switch to testing? Or reinstalling is the only way to go? Thanks
Re: Install Debian netinstall to HP Elitebook 840 G8 problem
Ok I am kind of getting what goes wrong. First configure boot options to usb in bios setting as usual. Then do rebooting. After the screen displays HP logo, pressing esc button, which will again enter the bios seting or that kind of screen but it will ask (the screen will display) with several options, such as continuous boot ... boot options bios setup ... Then this time, pressing continuous boot or something similar (sorry can't remember the name, but it's at the first option). Now it enters to normal boot process where lovely debian installer asks me to install or use gui blah blah It also possible my iso did not burn correctly. I did rebrun iso to usb using etcher, which seemingly do validation step. Anyway, hopes this trivial info may be of help to someone who also runs into some annoying issues (not debian side) similar like mine.

Install Debian netinstall to HP Elitebook 840 G8 problem
I purchased a new laptop HP Elitebook 840 G8, and am trying to install Debian to it. However I encounter a problem. I change the bios setting, but when booting from usb. What was shown on the screen is simply a grub env command line like grub> instead of a traditional debian install screen which may describe whether to install with GUI or standard mode (non gui). I've repeated installing from netinstall iso many times, but I had never run into such situation. So actually I am stocked. I don't know that's because of UEFI or because the iso burn to usb stick problem (but I check the usb I can see setup.exe, and those bootable files as usual w/t a problem). The netinstall iso is downloaded from [1]. Is it expected now to install debian from grub? Or maybe because the iso I download is broken? I am scratching my head. So I appreciate any comments or suggestions. Thanks! [1]. https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.0.0+nonfree/amd64/iso-cd/firmware-11.0.0-amd64-netinst.iso
Can't do apt-update because code name is changed from bullseye to bookworm
When doing apt-get update, debian throws following error. It looks like because the code name changed from bullseye to bookworm. E: Repository 'http://security.debian.org testing-security InRelease' changed its 'Codename' value from 'bullseye-security' to 'bookworm-security' N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details. E: Repository 'https://deb.debian.org/debian testing InRelease' changed its 'Codename' value from 'bullseye' to 'bookworm' N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details. N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'https://download.zulip.com/desktop/apt stable InRelease' doesn't support architecture 'i386' However in my sources.list is neither bullseye nor bookworm as below (I use testing-security). How can I fix this error?Thanks $ sudo cat /etc/apt/sources.list # security deb http://security.debian.org testing-security main contrib non-free deb-src http://security.debian.org testing-security main contrib non-free My environment are: $ cat /etc/debian_version 11.0 $ uname -r 5.10.0-6-amd64
ifneq problem
I have a Makefile used to check whether svn command existing or not. The content is below all: $(eval svnbin=$(shell basename $(shell which svn))) $(info X$(svnbin)Y) $(echo X$(svnbin)Y) ifneq ($(strip $(svnbin)),svn) @echo "$(svnbin)=/=svn" endif However, `make` command prints following to the console XsvnY svn=/=svn This is weird to me as it looks like no hidden character e.g. \n appended at the end of svn. The environment I have svn (1.14.1 (r1886195)) installed at /usr/bin/svn (`which svn`) Debian version bullseye/sid (`cat /etc/debian_version`) Make version 4.3 (`make --version`) Kernel 5.6.0-1-rt-amd64 (uname -r) What might cause this printout to console? Or anywhere I should check for debugging? Thanks
