I just installed Ubuntu on my machine and there is no wireless connection. I mean, the wireless card won't even show at the top pane of my desktop.  I might also add that whenever the Ubuntu launches, a moment before I get the login screen, there are three lines that say:   ERROR... something... something... wireless... go to www.kernel... something...     I don't know the exact words in the errors, because it vanishes a second after it appears, and it's too fast for me to read.  Is there a command that can detect my wireless card specification so I can look for a driver? or better yet, is there a command that can download the necessary drivers for the wireless card?   Here are the results for ifconfig:  eth0      Link encap:Ethernet  HWaddr 88:ae:1d:33:93:b0             inet addr:10.0.0.5  Bcast:10.0.0.255  Mask:255.255.255.0           inet6 addr: fe80::8aae:1dff:fe33:93b0/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:3539 errors:0 dropped:0 overruns:0 frame:0           TX packets:2922 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            RX bytes:3317067 (3.3 MB)  TX bytes:332509 (332.5 KB)           Interrupt:17   lo        Link encap:Local Loopback             inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:65536  Metric:1           RX packets:1119 errors:0 dropped:0 overruns:0 frame:0           TX packets:1119 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0            RX bytes:110448 (110.4 KB)  TX bytes:110448 (110.4 KB)   If any more information is needed, tell me.  Please, this is very important to me, I have a project due next week, and I cannot do it without wireless (I'm connected through wired connection right now).  EDIT: Here's some more information that might help, lspci -nn | grep 0280 gives:    04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible.   What are the steps to install Broadcom wireless drivers for a BCM43xx card?  I'm a user with no advance knowledge in Linux, so I would need clear explanations on how to make, compile, etc.    lspci -vnn | grep Network showed:   Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b]      iwconfig showed:  lo        no wireless extensions. eth0      no wireless extensions.

All windows I open have a black, boxy border, including popups, as you can see in the provided image. (The black box in the bottom right is a terminal, which fails to display any text. However, I can enter commands and they execute.) I followed the steps in this post:  to reset Unity using the unity-tweak-tool. Although helpful, that did not fix the issue.

How to fix invisible form fields in Firefox while using Adwaita Dark Theme (or any other dark theme) I have this issue with some form fields in Firefox and using the adwaita-dark theme. In some webpages where the field background is white, you cannot read the text because it is also white.   This question was edited in order to clarify that this kind of wording of the question might help people who are not familiar with what a GTK+ theme. I also thing that the wording will help to get more hits through search engines. If it's still considered a duplicate, I'll accept it.

How fast is Earth moving through the universe? As the galaxy is moving and the solar system orbiting the galaxy and the Earth orbiting the sun. So how fast is each object moving and what is the fastest we move at?  Do we even know how fast the galaxy is moving that is not relative to another galaxy (although I guess velocity has to be measured relative to something).

Usage of -n and -z in test built in - Bash Drag and drop not working inside Nautilus on Ubuntu 17.10 Getting MTP enabled devices to work with Ubuntu? Since Ubuntu 13.04 storage access to external devices via MTP is supposed to work out of the box via a GVFS-MTP module.      While this question is about the Galaxy Nexus, other Android devices as well as Windows Phones and MTP enabled media players are also supported.      For troubleshooting see .     I am having quite a bit of problems getting file-transfers working over MTP with the Galaxy Nexus. I am using Kubuntu 11.10 64-bit, and this is what I have done and the results I get:   Added rule for device in /etc/udev/rules.d/51-android.rules. The rule is the following and works for adb:  SUBSYSTEMS=="usb", ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="6860", MODE="0666", OWNER="leob" #Galaxy Nexus  Restarted udev (and computer just to make sure).   Adb works, and all methods for reading from the device via MTP seems to work (I have tried mounting with mtpfs, gmtp and using the mtp-tools package directly). When I try to write to the device however, nothing I have tried works.  As an example, running mtp-newfolder test_dir 0 0 gives the following output:  libmtp version: 1.1.0 Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7510/Galaxy Tab 10.1. Folder creation failed. ERROR: Could not close session!   If I run mtp-folders after a failed mtp-newfolder without re-plugging the device, I get the following output:  Attempting to connect device(s) Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7510/Galaxy Tab 10.1. PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device mtp-folders: Successfully connected Friendly name: (NULL) Error 1: Get Storage information failed.

EDIT:  I also tried the PTP mode. Again, reading works fine, but I cannot write anything to the device. Iterated self-composition of arbitrary function Does there exist some notation that represents the iterative composition of a single-input, single-output function with itself? As in, say, $f_5(x)=f(f(f(f(f(x)))))$.  In other words, going by the above (incorrect, I'm pretty sure) notation:  $f(x)=x+1$, $f_n(m)=m+n$  I'm looking for the correct way to express the notion of "$f_n(x)$" for any $f$. opengl storing multiple indices into indices buffer After parsing collada files I found out that we have to load two(or more) indices each pointing to say a vertex or normal etc. like this (&lt;p>3 0 2 0 0 0&lt;/p>)  Is there a way to load (and use)these indices to indices buffer(ELEMENT_ARRAY_BUFFER) like this (vnvnvn...) ; where v is vertex pointer, n is normal pointer from the above. with vertices loaded to VBO1 like (vvvv...) and in VBO2 like (nnnn...). So that we dont have to repeat the normals in VBO2.  VBO like (vnvnvn...) is also ok. (and not something like this ), I'm not trying to use multiple indices buffer. I'm trying to put all the given indices into one index buffer and use them alternately.
