Shutter capture functions are greyed after 21.10 upgrade

2

I have a computer and a laptop, both were running 21.04. But after I did the upgrade to release 21.10, I noticed Shutter Screenshot Tool is not functional anymore. All capture commands grayed, as you may notice by these attached images below.

I found a solution in issue 1353360 but it does not apply to me, because I don't wanna enable Wayland. And I already reinstalled Shutter under new PPA, without success.

Any ideas? I also posted the verbose when I launch the app here, to help. I think some component was discarded at upgrade moment, but I cannot identify which of them.

After upgrading to 21.10, .profile batch file is not being executed at session startup

0

Recently, I upgraded my computer to release 21.10. So I'm facing some issues related to it. Among then, .profile is not being executed when I login.

it's weird, because I used to have this kind of issue when I run Fedora, but never in Ubuntu - yet.

Any ideas? I'll post it below:

#sudo openvpn /etc/openvpn/strongvpn.conf &
pacmd set-card-profile 0 output:hdmi-stereo
bash /home/batch/AWS.sh &
bash /home/batch/gnetz &
bash /home/Programas/ums/UMS.sh &
shutter &
#grkellm &

PS.: it works when I execute it manually.

Does my motherboard disk controller faulty or somehow?

1

My computer became unstable since a week. First, I changed power supply. After that, I removed offboard video card, but no effect. So yestarday, it couldn't recognize my hard drive anymore.

I did a backup into another disk (Seagate - /dev/sda) and attached to my computer, where I started up a live usb Ubuntu 19.04. Same problems, same issues.

I changed SATA cables but no effect. Would my motherboard is faulty? How to determine it? Look at /var/log/syslog:

Look that my system tries to connect at 1.5 Gbps and 3.0 Gbps, UDMA/100 and UDMA/66 alternately.

Weird! I have another disk (SAMSUNG - /dev/sdb) stable at all. Look at lshw -C disk:

Cannot purge graphical interface from lubuntu 18.04

I installed lubuntu 18.04, so I wanna purge graphical interface, to make it run as a server, with just CLI enabled. But I can't!!

I already did:

sudo apt remove --purge lubuntu-*
sudo apt remove --purge lxde*
sudo apt remove --purge lxqt*

But it is starting with graphical interface with lightdm login screen.

Any ideas about how to get it?

How to prepare a server for proxy on Ubuntu 16.04

I'm trying to prepare a proxy server using Ubuntu 16.04, my server has the following nics:

          RX bytes:756664 (756.6 KB)  TX bytes:881724 (881.7 KB)

enp4s0 is WAN nic, connected to Internet. enp6s0 is LAN nic.

I configured them as it is on /etc/network/interfaces:

allow-hotplug enp4s0
iface enp4s0 inet dhcp

allow-hotplug enp6s0
iface enp6s0 inet static
address 172.24.3.19
netmask 255.255.252.0
gateway 172.24.0.1
dns-nameservers 172.24.3.1

enp4s0 received ip as follows, extracted from /var/lib/dhcp/dhclient.enp4s0.leases:

lease {
  interface "enp4s0";
  fixed-address 192.168.0.101;
  option subnet-mask 255.255.255.0;
  option routers 192.168.0.1;
  option dhcp-lease-time 7200;
  option dhcp-message-type 5;
  option domain-name-servers 192.168.0.1,8.8.8.8;
  option dhcp-server-identifier 192.168.0.1;
  renew 5 2018/06/08 16:03:17;
  rebind 5 2018/06/08 16:59:19;
  expire 5 2018/06/08 17:14:19;
}

Following Nairabytes.net, I applied some iptables rules as followed:

iptables -t nat -A POSTROUTING -o enp4s0 -j MASQUERADE
iptables -A FORWARD -i enp4s0 -o enp6s0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i enp6s0 -o enp4s0 -j ACCEPT

So iptables rules became as followed:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere             state RELATED,ESTABLISHED
ACCEPT     all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

But what I cannot understand is why just one of both nics works properly at a time. While this server can talk to LAN by enp6s0, it cannot connect to internet.

So I apply this route to it:

sudo /sbin/route add -net 0.0.0.0 gw 192.168.0.1 enp4s0

And the thing goes reverted! Now the server can connect to internet, but becomes unaccessible to LAN.

My original question was a try to set a gateway, but it seems to be impossible, because enp6s0 is LAN nic, and it's connected to a VLAN, better saying, this VLAN has already a Gateway (172.24.0.1) and I want to make this server visible to all others Subnets (not only 172.24.0.1 but we have other 12 subnets! All of them linked to 172.24.0.0 netmask).

So I decided to raise a proxy, not a gateway. I installed squid, but I must make connectivity to work before finishing squid configuration. My Network scheme is like at this figure: What am I doing wrong?

Ubuntu 16.04 empty purple screen after purging GUI interfaces

0

I installed Ubuntu Desktop 16.04 to raise a FOG server. After that, with all needed installed, decided to turn it to "Server", better saying, I purged these packages:

Unity;
Plymouth

ubuntu-desktop was purged with Unity automatically.

But, when I boot this server, instead of that classical black server splash (grub menu), I see the blank purple screen. And it takes over 2 minutes to show user login prompt, unless I force it by typing CtrlAltF1

Do I have to change something in grub config file? Anything else to purge or to install? I don't wanna to reinstall it, because here at work I cannot reach Ondrej repository, critical to reinstall FOG.

This really annoying freezing 17.10 Ubuntu switching user session!

3

I've seen several issues about freezing Ubuntu 17.10 GUI. I am facing this issue, too. It's really annoyng, but I believe my issue is more "accurated".

My computer has two RADEON GPUs, with three monitors. It's autologged by my wife'sdmseg account.

Funny is when I switch to my account. This Ubuntu release doesn't like to deal with two logged accounts. Because, while one account is active, the other freezes.

For example, I arrive home and login at 16:05. I work for about 30 minutes. When my wife needs to work and we switch session, the clock at her session is showing 16:05! Frozen. Just the mouse moves on, nothing more. Sometimes, session is unlocked, and everything goes normal. But sometimes, the only solution is:

sudo pkill -u <username> -KILL

Here is dmesg -T output:

How to enable Dropbox panel icon at startup in Lubuntu?

3

I installed Dropbox in Lubuntu. It works perfectly, but panel icon is not shown, because Nautilus is not default file-manager in Lubuntu.

I've been searching for several forum pages at Askubuntu, Ubuntuforums and ArchLinux Forums. They doesn't work entirely in Lubuntu. The best I got is this icon, that is shown in this image,

but it doesn't work at all.

So I ask: Is there any solution for Dropbox Panel Icon in Lubuntu?

Cannot switch user from autologged account to another account

My computer is running Ubuntu 17.04 and has my wife autologged in. When I want to switch to my account, by clicking to switch at top-right desktop:

This works most of the times, but sometimes I just get a black screen.

I extracted a piece from /var/log/auth.log when it occurs:

Aug 31 21:43:09 olimpio lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory

Aug 31 21:43:09 olimpio lightdm: pam_unix(lightdm:auth): auth could not identify password for [robson]

At this very time, I see this in /var/log/syslog:

Aug 31 21:43:09 olimpio lightdm[1618]: Stopping PAM conversation, interaction requested but not supported

I have to reboot my computer at this point, because my session is planned to execute scripts at DISPLAY :1, if I log at DISPLAY :0, my scripts will cause a problem.

Can anyone help me? I found that there are two similar issues (127147 and 635978), but those didn't solve my problem.

Export 16.10 internal error reporting to a file

Does somebody knows how I can export an error box that my computer shows everyday to a file? I'm running 16.10-64bit and I tried Copying and pasting, but the box allows copying just topic-by-topic. The error I wanna deal with has more than 30 topics!!!! I tried to post an image, but it's not allowed to me. The box has a following message at top: "Sorry, Ubuntu 16.10 has experienced an internal error." Thanks!

Why when I install some packages using apt, I receive a message like this:

dpkg: aviso: falta ficheiro de lista de ficheiros 'install-info'; assumindo que o pacote não tem actualmente ficheiros instalados

Translating to

dpkg: Warning: Missing file from filelist 'install-info'; assuming that package has not installed files

It's not critical, because I can install something, but... Why this message?
