I am having trouble running Ubuntu on a custom made desktop (some specs below). The problem is that at a certain point my monitor shuts off and gives me the message:   The current input timing is not supported by the monitor, Please change your input timing to be 1920x1200@60Hz   Initially I was having this problem during installation, so when the first purple screen would come up I hit the down arrow and set nomodeset and added "vga=0x14d" to the end of the command. This allowed me to continue without getting the above error on my monitor. Once installation was complete I edited /etc/default/grub to include the line:  GRUB_GFXMODE=1920x1200   Then I entered:  sudo update-grub   And restarted the computer. Now when I get to the Grub screen, everything is fine but after the that I again run into the input timing error. I have tried various permutations and combinations in the edit screen but I can't seem to set the resolution properly to actually see Ubuntu once it has started up.  Relevant specifications: Ubuntu version: 16.04 Motherboard: Asus X99-E GPU: Nvidia GTX 1080 Monitor: Dell U2412M  EDIT: The motherboard does not have an integrated graphics card. EDIT2: I tried following the answer for , however setting nouveau.modeset=0 at the end of the line that begins with "linux" does not work, I still get the input timing error above and if I cannot boot into Ubuntu then I am unable to install drivers.
I am using Ubuntu 16.04 with GTX 1080. On my first boot, the screen turn black after I selected Ubuntu in grub. After I added nomodeset, the black screen gone however it only shows the Ubuntu default background image. It can't reach the login screen.
I'm running a VPS of a german provider and want to switch from Ubuntu to CentOS. There I tried to install firewalld (was not preinstalled), but it always fails with the error  ERROR: Failed to load nf_conntrack module: modprobe: ERROR: could not find module by name='nf_conntrack' modprobe: ERROR: could not insert 'nf_conntrack': Function not implemented modprobe: ERROR: Error running install command for nf_conntrack modprobe: ERROR: could not insert 'nf_conntrack': Operation not permitted   Obviously the nf_conntrack kernel module was not found. Since this is a VPS, I cannot tinker with the kernel modules. On the support site of my provider I found a list of available kernel modules, for example:  ip_conntrack_netbios_ns ipt_conntrack    ip_conntrack    ip_conntrack_ftp    ip_conntrack_irc   Since nf_conntrack is not listed here, does that mean, that I cannot use firewalld? Is it possible to run it without this module?  I guess I could use iptables, if I wanted to (it seems to run correctly). But as I have more experience with firewalld, I would like to stick with it.    CentOS Linux release 7.7.1908 (Core)  uname -a: Linux xxxxxx.xxxxxxxx.xxx 3.10.0-042stab140.1 #1 SMP Thu Aug 15 13:32:22 MSK 2019 x86_64 x86_64 x86_64 GNU/Linux Introductory Calculus textbook for physics? I have the summer to prepare myself for a high school calculus-based physics course; however, I will have to study calculus by myself. I've completed a course in precalculus and I'm beginning to read .   I am looking for a textbook that has mathematical rigor (i.e. not memorizing formulas), yet also provides adequate foundations for a physics course. From similar stack exchange questions, my top candidates are  and . Which one of these textbooks, if any, would be the best choice for my situation? Implementing i18n string translation in a custom module? I have a custom module I've built which essentially acts as a repository of custom CTools keywords that users can arbitrarily define. The issue I'm facing is I need to be able to translate these user-defined strings, so I think I need to implement string translation using the i18n_string module.  I have never worked with translation or localization before, so I'm a bit lost with regards to going about how to implement this. I think I'm on the right path with i18n_string though. Can someone experienced with i18n provide examples that I can look at so I can learn the proper way to implement this? I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this. The observable universe is approximately 13.7 billion years old. But yet it is 80 billion light years across. Isn't this a contradiction? I thought I'd post this as it illustrates a problem often encountered on ELU.     In structures such as 'football manager', is 'football' a modifier or   a complement of the head noun?   I've seen both terms used as if there were only one possible correct answer. However, I've come across widely differing definitions of both 'modify' and 'complement' as used in grammar. I believe that people stating baldly that this is either one or the other are assuming a grammar that they prefer, rather than giving a balanced overview.  Notice that I intend this question to explore the usage/s of the term 'modify' and of the term 'complement' in this context. There may be overlap with the question of which word-class 'football' fits into, but that decision hardly answers the question. Is this mold? Black? White? Guys I need to find out what this is- it's also on my wooden bed racks Understanding GeoTIFF tags? Is it possible to assign the same value to multiple keys in a dict object at once? I need to update a vector layer's data when the visibility is turned back on.  My update does not occur when the visibility is off.  To what signal do I need to connect to catch the visibility change? Points of a Measure Zero Sets Covered by Intervals Infinitely Many Times Given a measure zero set $E$, by definition we have forall $\varepsilon &gt; 0$, a covering of $E$ by intervals whose lengths sum to $&lt; \varepsilon$.  I want to prove that we can cover $E$ in intervals such that the sum of the lengths the intervals is $&lt; 1$ and each point in $E$ is contained in infinitely many of the intervals.  Do you know how to prove this? Thank you Is it possible to download using the Windows command line? Without using any non-standard (Windows included) utilities, is it possible to download using the Windows command line?  The preferred version is Windows XP, but it's also interesting to know for newer versions.  To further clarify my question:   It has to be using HTTP The file needs to be saved Standard clean Windows install, no extra tools   So basically, since everybody is screaming , I want simple Wget functionality, without using Wget. So I am using  package for code examples. But there is a problem. When I copy the code examples from the final PDF document, they are usually not the same - the indentation is gone, there are random spaces after parenthesis, etc. Does anyone know how to make sure that the code that I copy from the final document is the same as I wrote it in the LaTeX document?  Here is what I mean. Compile this document:  \documentclass[12pt,oneside]{memoir}  \usepackage{listings} \usepackage[T1]{fontenc} \usepackage{xcolor} \usepackage{textcomp}  \definecolor{codebg}{HTML}{EEEEEE} \definecolor{codeframe}{HTML}{CCCCCC}  \lstset{language=Awk} \lstset{backgroundcolor=\color{codebg}} \lstset{frame=single} \lstset{framesep=10pt} \lstset{rulecolor=\color{codeframe}} \lstset{upquote=true} \lstset{basicstyle=\ttfamily} \lstset{showstringspaces=false}  \begin{document}  This code example prints out all users on your system:  \begin{lstlisting}[language=c] #include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; #include &lt;string.h&gt;  #define MAX_LINE_LEN 1024  int main() {     char line[MAX_LINE_LEN];     FILE *in = fopen("/etc/passwd", "r");     if (!in) exit(EXIT_FAILURE);      while (fgets(line, MAX_LINE_LEN, in) != NULL) {         char *sep = strchr(line, ':');         if (!sep) exit(EXIT_FAILURE);         *sep = '\0';         printf("%s\n", line);     }     fclose(in);     return EXIT_SUCCESS; } \end{lstlisting}  \end{document}   Now compile it, open it, select and copy the code example and paste it in a text editor. Here is the result I get:  # include &lt;stdio .h&gt; # include &lt;stdlib .h&gt; # include &lt;string .h&gt; # define MAX_LINE_LEN 1024 int main () { char line [ MAX_LINE_LEN ]; FILE *in = fopen ("/ etc / passwd ", "r"); if (! in) exit ( EXIT_FAILURE ); while ( fgets (line , MAX_LINE_LEN , in) != NULL ) { char * sep = strchr (line , ':'); if (! sep ) exit ( EXIT_FAILURE ); * sep = '\0 '; printf ("%s\n", line ); } fclose (in ); return EXIT_SUCCESS ; }   Jeez! What's this... The indentation is gone. There are spaces in included headers &lt;stdio .h&gt;, there are spaces after parenthesis [ MAX_LINE_LEN ].  Anyone knows how to fix this? I'd like the code examples in my book to be copy/paste-able into a text editor so people can try them out easily. Can't install php5 on Ubuntu 16.04 so I've recently installed my first Ubuntu, to be precise, a daily build of 16.04, on my new laptop since the hardware was to new for 15.10. Now I'm in the process of setting it up and I want to install php5 and some extensions.  When I execute sudo apt-get install libapache2-mod-php5 I get the error message that there is no installation package available for php5 and libapache2.  The error message is in german, so I doubt that this would help, but anyways here it is. :-) E: For package »libapache2-mod-php5« existiert kein Installationskandidat.  Do I need to add a apt-get repository? Or what am I doing wrong? Bohr's model of an atom doesn't seem to have overcome the drawback of Rutherford's model I've been writing checks this way for the last ~15 years or so:    Namely, the amount field is written using numbers like     1,500 and 00/100    rather than the tedious, painful spelling out of      One Thousand Five Hundred and 00/100   99 times out of 100, this works fine. But occasionally you'll get certain rare human tellers who simply refuse to believe this is a valid check and you have to fight over it. I still figure the time I've saved by not writing out all those ridiculous numbers-as-words is still worth it, overall, but it's definitely irritating.  So: who's right? Is a check with the amount written in numbers valid ... or not? How does electricity propagate in a conductor? How can I change the default date format? When I paste a date into Excel 2010 in the format "2012-12-07 00:00:00.000" I'd like it to be displayed by default as "2012-12-07", but it is actually displayed as "00:00.0".   I know I can work around this by prepending a ' or changing the cell format, but I'm interested in changing the default format.  An approach that almost works is going to Control Panel->Region and Language->Long Time format and changing it to something like "h". This results in Excel displaying the dates I paste in as "2012-12-07 00:00:00.000", but screws up times displayed outside of Excel.  The dates I'm pasting in are from SQL Server. Two  have been announced in LoL.  They have an ability that makes them be able to recall together.                                  What are the limits to this ability? Can the 'non-recaller' jump in at the last second and get some kind of instant recall?  Can somebody with the setup to get on PBE test it and tell us what are the limitations of this ability?
