laptop – Ubuntu hangs during suspension on Lenovo E490

This is a brand new Lenovo E490 running Ubuntu 19.04, using the kernel 5.0.0-25-generic. Almost every time it is hanging on closing the lid, it locks and can only be recovered by long pressing the power button (forced shutdown).

Of /var/log/kern.log – I think that closing the cover was at the beginning of this diary 12:47, and it seems that several attempts to suspend have taken place. 13:39 is the boot after the hard stop.

Any ideas on how to look for this further?

What should be changed or removed to replace elementaryOS with Ubuntu 19.04 while keeping Windows?

I want to completely erase the basic operating system and install Ubuntu 19.04
The installer offers me 2 choices-
Install next (what I do not want)
Another thing (I want to keep Windows and install Ubuntu to replace Elementary)
What next steps should I do?
Which partitions do I have to delete / modify?

Ubuntu 19.04 crashes on startup

So I recently started Ubuntu and Windows 10 in duplicate on my PC because I was curious to see if I could possibly replace Windows 10 with Ubuntu. I've installed Ubuntu, but every time I start on Ubuntu, the startup logo appears, and then the screen is cut off on the screen. Sometimes it gets stuck on "Started Hostname Service" or "Reached Target Bluetooth", its almost different every time and I do not know if it's something I'm doing wrong. I did some research and I managed to use Alt + F2 and use the "startx" command to start Ubuntu, but the loading is still not complete. Please do not use technical language because I am very new to Linux.

hard drive – Duplicate Ubuntu Disk

I have Ubuntu 18.04.3 on a mechanical drive of 500 GB. I am added a SSD. I installed Ubuntu 18.04.3 on the SSD. The SSD is sda and the mechanical disk is sdb. Both discs have the same number of sectors.

I have more than a year of system changes installed on the mechanical disk.

I want to duplicate sdb on sda. Is it possible?
If I start sdb,
& # 39; Sudo dd if = / dev / sdb of = / dev / sda bs = 2G & # 39; work there?

Is there a simpler way to duplicate the installation?
I especially want the apt and python packages to be the same.

Ubuntu – Hotlink – Nginx – WordPress – Vesta Cp

I need your expertise since using Vesta cp (Apache and Nginx).

The normal code for the hotlink link works on an Apache server, but on my new server it does not work because it's nginx, but any other code you put on htaccess works, except for the code hotlink. (Note I tried to test it on an Apache server and its operation)

Can you help me implement hotlink on a nginx server? I tried to edit and add this code to the following location

/home/admin/conf/web/mydomain.com.nginx.conf (if I add my code here, the nginx works perfectly but its action or direct link does not work)
/etc/nginx/conf.d (when I add my code on this file, the nginx does not start)

Code for hotlink Nginx

location ~ .(jpe?g|png|gif|jpg)$ {
    valid_referers none blocked mydomain.com *.mydomain.com;
    if ($invalid_referer) {
        return 403;
    }
}

htaccess code

No sound in ubuntu (ZORIN) [on hold]

I know a lot of people ask me, but I tried many things, but nothing solves my problem.
I do not have sound and I do not have the sound symbol (see photo), and also in parameter I have no output and the button is gray. I'm looking for a solution for a week!

ubuntu – Traffic tunnel from one proxy server to another

I want to configure a certain configuration, but I'm not sure which tools and / or names to look for to get more information about it.

I have the following configuration:

Client                         / Requests to public internet
Client - > Shadowsocks Server > - Requests to public internet
Client /                         Requests to public internet

It works, but I want to add another server to the combination and tunnel requests to the public Internet to another proxy server before sending them.

Client                                        / Requests to public internet
Client - > Shadowsocks Server > Proxy Server > - Requests to public internet
Client /                                        Requests to public internet

My initial idea was simply to use tinyproxy on the second server, but I did not know how to transfer requests from the first server to the next. As far as I know, shadowsocks-libev, which is the proxy server on the first server, does not have parameters to transfer traffic to another server.

So now, I have no idea how to do it or what to use. Any help is very appreciated.
