SER sometimes requires “two clicks” to bring window to front

Hi @sven, a bug I’ve noticed since have been using SER a lot lately. In Windows 7 (possibly Windows 10 as well), SER requires “two clicks” when you have a project running and navigate away from the SER window.

To re-create the bug:

– Open SER
– Start a project (make active)
– Click to another taskbar program, for example, Excel
– Wait a while, don’t click on SER immediately after
– Click on SER icon in the taskbar
– SER doesn’t recognize the click, the window does not open
– Click SER taskbar icon again and it will show properly

This is a small but really annoying issue as when a program is clicked you would expect it to appear accordingly. It could be a Windows problem, but I’ve never encountered this with any other program besides SER.

Update: I actually just had this issue without an active project. Does SER have some sort of “sleep mode” that requires 2 clicks to re-open the window after you haven’t clicked it in the while or something?

Sometimes run..sometimes not…in /etc/init

Env : Ubuntu 10.04

One file is created under /etc/init to run at boot… Actually, I have a couple of files created under here..but only one of files has some issue…Sometimes this one runs….sometimes not… If I rebooted my machine, then..it runs sometimes..sometimes not, I had to reboot a couple of times to see the process I set up to run actually running… What could be possible reasons? Initially I thought that this may be run before setting PATH env variable ..so..I tried specifying the absolute path..but still……the behavior still same….sometimes it runs or not after my machine is booted…What could be possible reasons you can think of? Any good way to check why this particular one have this issue?

Thanks,

Laptop sometimes shows underscore in corner, becomes unresponsive when opened

I have a Dell XPS 15 with a GTX 1050 GPU running Ubuntu Budgie 19.04, and I have the 418 drivers. Recently, my laptop has been occasionally having a problem where when I open the laptop, instead of showing my lock screen, it shows a black screen with a small underscore in the upper left corner. Sometimes I can press ctrl-alt-f1 to see a login prompt, but I can’t type anything or switch to any other console. The only way to use my computer again is to hold down the power button until the power is cut and turn it back on again. What is causing this, and how do I fix this?

DNS and sometimes TCP packet are being sent out upon disconnecting and connecting wifi connection

I am monitoring my network interface and noticed that I can reproduce a behavior where some cryptic DNS packets are being sent out as well as TCP sometimes, without me opening any browser or application for that matter.

All I have to do is turn off WIFI and then turn it back on. Then a number of DNS packets are sent out automatically.

Here is the cap file:

enter image description here

This doesn’t strike me as normal behavior, why are DNS packets being sent out?.. Upon following the TCP packets I noticed that they are being sent to an EC2 instance on AWS.

Thinkpad T430, Ubuntu 18.04, No sound on startup sometimes

Sometimes I have sound when I start, sometimes I don’t. Rebooting has always fixed it so far…

Lenovo Thinkpad T430, Ubuntu Studio 18.04. No sound from headphones or speakers. Sound buttons on top panel don’t do anything.

I’d kinda like to have some tips on troubleshooting this from the terminal. ‘aprops’ suggestions, i.e.

Swift HMAC doesn’t match NodeJS HMAC, but only sometimes!

I have discovered a HUGE issue in my code, and I have literally no idea what is causing this.

SO, when I send requests to my server I hash a string thats in the request. This is sometimes user input.

My app is multi language so I have to support all “ä” chars etc.

So with the normal english letters/chars numbers etc, this hashing method works like a dream. BUT when the string being hashed and compared contains a “ä” or a “ö” (Not specifically those, it literally might be that any char not in the Base64 set will cause this) the hash doesn’t match!

This is an absolute and complete disaster, and I have not noticed it this far. I have tried basically everything I know to try to fix this, and googling, and I am out of luck so far.

I generate the hash in Swift inputting the string and secretToken into this function and saving the output as a HTTP header:

func hmac(string: String, key: String) -> String {      var digest = [UInt8](repeating: 0, count: Int(CC_SHA256_DIGEST_LENGTH))      CCHmac(CCHmacAlgorithm(kCCHmacAlgSHA256), key, key.count, string, string.count, &digest)      let data = Data(digest)      return data.map { String(format: "%02hhx", $  0) }.joined()  } 

How I compare the hash in NodeJS:

if (hashInTheRequest === crypto.createHmac('sha256', secretToken).update(stringToHash).digest('hex')) {     //Good to go } 

Thanks in advance!

Monitor process, because writing stuck sometimes for 1 second

System

Linux local 5.0.0-27-lowlatency #28-Ubuntu SMP PREEMPT Tue Aug 20 20:33:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 

Issue

Sometimes, when I am writing, cursor stuck for second and then it write many same chars, form example rrrrr, etc.

I believe this is caused by some process.

Question

Is some good tool for monitoring and search which process do it? I tried top, but quite difficult to find “bad” process. Better no GUI app please.

I have suspicion for these processes (in evolution, when answer email as RE), or java process (dbeaver).

Question 2

Is possible to do something with that? For fluent running of system.

Thanks.

Why does clicking by both mouse and touchpad sometimes stop working?

I am using Lubuntu 18.04.

Sometimes, when I am using Firefox to browse webpages or some other applications, clicking ( left, right and middle) by my mouse and touchpad stops working, although I can still move the cursor using my mouse and touchpad. It is as if there were something else which is invisible and stands between the screen and the applications’ windows and steals clicks away.

In that situtation, if I switch to log into another user account, the problem disappears. But when I log back to the original user account, the problem remains.

What may cause the problem? It is unlikely the drivers or modules for the mouse or touchpad, since clicking after switching account still works. Can the cause come from the window manager openbox, lxsession, or something else?

What shall I do to solve the problem? Restarting Lubuntu is the least thing I want to try, every time when the problem occurs.

Thanks.
