I am running Ubuntu 20.4 and via the settings GUI I configured it as access point to share the wired connection to other devices (ubuntu computer, android smartphones).

The access point starts, the other devices see the SSID, password is correct, but the access point does not assign them an IP address; client devices wait for an IP address forever...

With

ifconfig -a

I see the AP ip address, netmask and gateway (10.42.0.1/24)

I statically assigned addresses to the other devices (10.42.0.2...5) and they can access the internet.

What shall I do so that the AP serves ip addresses to the connecting clients ?

One would expect that all needed pieces work automatically... Shall I install a DHCP server ?

Any help highly appreciated.

P.S. I have a second, less relevant question :

nm-connection-editor

doesn't allow me to change channel number. The field is not editable.

What shall I do to chanhe channel number ?

Again, thanks for your help!

How to change splash/login screen/color in Ubuntu 20.10 ?

I have read many posts on how to change splash/login screens (or at least change its purple color) for versions of Ubuntu prior to 20.10 which is the one I'm running.

I've been able to change the login screen color by changing the background image but changing a background image just to change the background color seems a little overshooting. is there a simpler way to change just the background color ? (for those of us who don't like purple).

Is there a way to change the splash screen as well ?

Any help highly appreciated!

I am transitioning from windows to ubuntu; I run 20.10 with Gnome in a partition of my disk. I mount the windows ntfs partition's on /home/myname

My windows desktop, where I have a lot of my stuff, is therefore accessible at /home/myname/Users/myuser/Desktop

I configured in .config/user-dirs.dirs the desktop directory to /home/myname/Users/myuser/Desktop

Up to this point everything looks ok: all of my windows desktop's files appear within ubuntu like this.

icons from my desktop

If I change an icon, for example of folder 'Libro', by editing the folder's properties, it doesn't change on the desktop but if I open a nautilus browser to that same directory, it correctly displays the new icon.

enter image description here

this is the first weird behaviour

a second even worse behaviour is that, when I try to drag an icon to an app (for example a file to be attached to a thunderbird email) the mouse cursor becomes a closed hand (looks like a fist) and the computer hangs. the mouse is movable; if I close the notebook it suspends, when I reopen it, the only possibility is to enter the password in the lock screen; after the lock screen I get back to exactly the same point with the computer still hanging.

my only possibility is to abruptly power off and reboot.

I wonder if the cause of both behaviours can be an issue with permissions/file system mounting.

After some trial and error, in my /etc/fstab I entered

UUID=2E54F0D254F09E31 /media/myname ntfs rw,auto,user,fmask=111,dmask=000,uid=1000,gid=1000 0 0 which works quite ok, except for the to issues above.

but if I look at mount, I obtain

/dev/sda2 on /media/myname type fuseblk (rw,nosuid,nodev,noexec,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,user)

Here goes the question: may it really be an issue with the mounting of the filesystem ? any hints on how to fix it ?

any help highly appreciated...

happy 2021!
