I am aware there are questions with similar names, but I think the problem is different. Such as the following:
However, what I am experiencing is quite different. Let me first describe it a little in detail. I have a dual-booted HP Pavilion laptop with 64-bit Linux mint and 64-bit Windows 10 Operating systems. The following issue is in both operating systems.
left ctrl+tab: does not work
left ctrl+shift+tab: works
left ctrl+t: does not work
left ctrl+Pgup: does not work
left ctrl+PgDn: does work
right ctrl+tab: works
right ctrl+shift+tab: does not work
right ctrl+t: does work
right ctrl+Pgup: does work
right ctrl+PgDn: does not work
I thought the behavior is attributed to Nvidia. However, a system restore would not fix the problem. I also tried uninstalling all the Nvidia software off my computer which proved to no avail. I rebooted Windows in Safe Mode and the problem still persisted. The hotkeys do not work anywhere: not the browser, task manager, etc. When I use an external keyboard, all functionality is available Help would be greatly appreciated!
I do not think it is related to my laptop, but here is my laptop model:
HP Pavilion - 15t Laptop; Product number: M7H64AV

Does Left-Ctrl function for other key combinations, or does it not function at all? In the later case, verify the physical keyboard and the registry Keyboard Layout.
– harrymc – 2016-04-03T10:08:35.2101@itzjustricky Can you connect an external keyboard and check whether the key combinations work? – rahuldottech – 2016-04-03T14:10:49.033
@RahulBasu the key combinations work with an external keybord – itzjustricky – 2016-04-04T01:18:35.120
@harrymc they Left-Ctrl function for some key combinations. – itzjustricky – 2016-04-04T01:19:46.487
Sounds like it might be a problem with key rollover, but that would be quite ridiculous to have it happen with two keys. Most keyboards should be a minimum of 3-key rollover Is the laptop new? – Bob – 2016-04-04T01:59:10.513
@Bob yeah the laptop is quite new – itzjustricky – 2016-04-04T02:05:03.537
@itzjustricky Can you test an in-store model to see if it has this problem? Can you return it under warranty? It really sounds like a hardware issue. Oh, and check the settings in the firmware (BIOS/UEFI) to see if there's anything that might be relevant - I know HP laptops like to have at least a fn-related setting. – Bob – 2016-04-04T02:07:32.480
@Bob I will try to see if I can test an in-store model, but the laptop was fine for the first 4 months I had it. I have tried switching the BIOS settings to see if it would have an effect. Switching the fn-related setting on and off did not seem to change anything. – itzjustricky – 2016-04-04T02:10:26.593
1@itzjustricky Did it start happening after a software installation or update? It's really sounding like a hardware problem to me, and therefore warranty-worthy. – Bob – 2016-04-04T02:13:06.710
