I've installed Linux Mint 18.2 on my ThinkPad E470. I can't connect to wifi as no wireless option shows up. I searched around and found an old post with the exact problems as mine - https://ubuntuforums.org/showthread.php?t=2187780. But the solution to it is old and doesn't work for the new linux. And, lspci doesn't list my wifi adapter model. I also tried the solution given by Pilot6(Can't post the link as i have an upper limit on no. of links). But it doesn't work. This is the output of lspci -knn | grep Net -A2. https://pastebin.com/mMa6465h

Worked solution (Requirements: kernel >=4.11) :



(UPD: In the latest release of endlessm you need kernel version 4.15)



  1. Download driver directory from this repo:
    https://github.com/endlessm/linux/tree/master/drivers/net/wireless/rtl8821ce

You can do it by this link:
https://minhaskamal.github.io/DownGit/#/home?url=https://github.com/endlessm/linux/tree/master/drivers/net/wireless/rtl8821ce



  1. Unpack zip archive.

  2. Change the Makefile. Line "export TopDIR ?= ..." to export "TopDIR ?= PATH TO EXTRACTED DIRECTORY".

  3. make

  4. sudo make install

  5. sudo modprobe -a 8821ce





share|improve this answer






















  • Thanks for the tip - that worked for me. It failed with kernel 4.11.12 though and I had to upgrade to 4.13 in order to make it happen. Also, fwiw, kernel-devel should be installed as well (for new installs)
    – Mario Peshev
    Nov 27 '17 at 21:32











  • I have written something like this, export TopDIR ?= /Downloads/rtl8821ce And get an error message like this, $ make Makefile:821: /Downloads/rtl8821ce/rtl8821c.mk: No such file or directory make: *** No rule to make target '/Downloads/rtl8821ce/rtl8821c.mk'. Stop. Any idea what am I missing here?

    @HaseebMahmud, 1. Check if the file rtl8821c.mk really exists in the folder that you downloaded. 2. Probably, you wrote the wrong path in 'export TopDIR'. Try to wrote full absolute path there.
    – Eugen
    Feb 23 at 2:53











  • @Eugen Thanks. My mistake was not writing the "absolute path". It should be /home/username/Downloads/rtl8821ce instead of /Downloads/rtl8821ce. It works now.

Clash Royale CLAN TAG #URR8PPP 1 How can I extract a single band from multi-band raster in QGIS? I have an remote sensed image which has 6 bands (including NDVI band), I want to display each band separately, but have no idea how to do. I have seen some questions similar here but none worked for me. The original image (has 6 bands) is: I want to display the band 6 which should be like this: But I tried gdal_translate, and couldn't get the correct result.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
