Ubuntu 14.04 Desktop lost open app windows after waking up from the sleep mode

Question

I am new to Ubuntu Desktop but have used Windows and Mac for a long time. I also have good experience with Linux. I need some help on how to recover the lost app windows.

I have been quite impressed by Ubuntu Desktop so far until I run into this problem. I use Ubuntu 14.04 Desktop on a Toshiba laptop with an external monitor. I use Chrome browser and Terminal apps frequently to develop software. I need to keep these app windows open for several days. I put the laptop into sleep mode between work sessions.

I often find some open windows are lost after waking up the laptop from the sleep mode. For example, I use Chrome browser to research topics. After waking up the laptop, I cannot find the Chrome window anymore. I can open a new Chrome window from the Chrome icon on the launcher. After that, if I click the Chrome icon on the launcher again, I can see both Chrome windows. But I cannot choose the old one.

This happens to both Chrome and Terminal apps so far. Can someone give me pointers on what I might have done wrong? Thanks.

I don't think you're doing anything wrong that may cause this problem.

Ubuntu 14.04 uses the relatively new Unity user interface that a still has a few rough edges, as well as a more recent Linux kernel (3.13+).

Many of us are having a series of issues:

14.04: password not accepted after computer wakes up from sleep https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1299778 https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300

From time to time Chrome has also crashed for me (you should see an Apport dialog showing up when that happens), especially after waking up the computer.

Try searching Ubuntu bugs in Launchpad and if nothing like your problem shows up for 14.04, consider filing a new bug report. This is your best shot at getting the issue fixed.
