  • Is there a way to force lubuntu screen resolution?

    - by za1
    I have a Dell Inspiron 4000, 900 Mhz Pentium III, 192 MB RAM,10.1 GB disk running Lubuntu 12.04. When I start the computer, and I check the display resolution, Monitor Settings claims that the max resolution is 1024x768. I then connected another monitor I had lying around, rebooted, and now the laptop monitor looks normal,and monitor settings claims that 1280x1024 is the max resolution (it is) and the other monitor doesn't turn on. (black screen) The external monitor is not broken. Is there a way to, without the external monitor, force the laptop monitor resolution to 1280x1024? (The following is another question) - How can you run commands automatically at startup? Specifically "xinput 18 118 0" (without quotes) The first question is important, I can live with typing the second one at every boot. Thanks

  • Visitor-pattern vs inheritance for rendering

    - by akaltar
    I have a game engine that currently uses inheritance to provide a generic interface to do rendering: class renderable { public: void render(); }; Each class calls the gl_* functions itself, this makes the code hard to optimize and hard to implement something like setting the quality of rendering: class sphere : public renderable { public: void render() { glDrawElements(...); } }; I was thinking about implementing a system where I would create a Renderer class that would render my objects: class sphere { void render( renderer* r ) { r->renderme( *this ); } }; class renderer { renderme( sphere& sphere ) { // magically get render resources here // magically render a sphere here } }; My main problem is where should I store the VBOs and where should I Create them when using this method? Should I even use this approach or stick to the current one, perhaps something else? PS: I already asked this question on SO but got no proper answers.

  • Error after installing Lubuntu 14.04 through liveUSB

    - by Veritas
    A friend asked me to install ubuntu on his toshiba NB 200 netbook to replace windows xp. I formatted the flash drive, ran an nb5sum check on the iso and after running netbootin , I checked the drive for errors. No problems so far. During the installation, while everything seemed normal, the installation regularly paused until I pressed a button or moved the mouse. After restarting, it doesn't boot and it starts a shell showing : "General error mounting filesystems A maintenance shell will now be started CONTROL-D will terminate this shell and reboot the system " Any ideas? Any help is appreciated!

  • Samsung NC10 Broadcom difficulties

    - by simonp
    I am new to Ubuntu/Linux and am stuck already! Any help much appreciated. I have managed to install Ubuntu Maverick 10.10 (from a USB flash drive) on my NC10 which also has Windows 7 on the partitioned drive. But the wireless internet is not working. I have identified the hardware as a Broadcom BCM4313. I have also managed to find that the correct driver is installed (Modaliases for Broadcom 802.11 Linux STA driver). I have followed advice from elsewhere and there does not seem to be any competition from other drivers. I am now stuck and do not have any other internet access on this netbook. Any ideas?

  • If you need more than 3 levels of indentation, you're screwed?

    - by jokoon
    Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduct from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that dividing up a program into more function improves its design is a common thing taught at school, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

  • Partition showing up twice under devices

    - by JohnReed
    I have an ntfs data partition on the same drive as my ubuntu 12.04 partition. I wanted to have this partition automatically mount at startup so that dropbox can start syncing at startup without me having to manually mount it (my dropbox folder is on the partition). I edited the fstab file by appending the following to it: #Data-Partition UUID=762639DE416D0A21 /media/Data ntfs-3g rw,auto,users,exec,nls=utf8,umask=003,gid=46,uid=1000 0 2 The drive now automounts at startup like I wanted, but now I have a duplicate Data entry under my Devices list. This only appeared after editing the fstab file. The second Data entry under Devices does not mount properly and I do not want it there. Why is this duplicate entry there and how can I get rid of it? additional information: Here is the output I get from cat /proc/partitions: major minor #blocks name 8 0 976762584 sda 8 1 102400 sda1 8 2 111574016 sda2 8 3 803643392 sda3 8 4 1 sda4 8 5 55410688 sda5 8 6 6028288 sda6 11 0 1048575 sr0

  • Installer doesn't recognise windows 7 install

    - by SirWaffleRaptor
    I will start off saying I searched a bit for this problem with little success. You see, I am an utmost noob when it comes to Ubuntu and Linux based OS (hence why I want to install it and discover it) and the thread I found were too specific for me to do anything with. Therefore, if you find a thread that is noob-friendly and answers my question, please link it below or please try to answer as simply as possible :) The problem: I want to install Ubuntu 12.04 LTS 64 bit alongside Windows 7 on my main hard drive (to get the choice which one to start when booting). Pop the CD in, reboot and get to the installer screen. I know I'm supposed to have 3 options, but I'm only given the option to erase my hard drive or "do something else". Therefore, my question is: how do I make Ubuntu recognise Windows 7, so it may install alongside it?

  • Does booting a live USB cause writes to occur to it?

    - by InkBlend
    I know that Ubuntu will not and can not write to a live CD-R/DVD+-R when it is booting from it, as it is a read-only medium. However, the procedure (at least on the data level) for running Ubuntu off an optical disc is different from a USB drive, which is usually write-enabled. if I make a live USB, turn off persistent files, and boot from it, will any data be written to the USB drive (e.g. settings, error logs, temporary files)? Or will Ubuntu just read from it, nothing else?

  • Inserting x200s into (ultrabase) docking station mirror screen is always activated leading to non optimal resolution

    - by kiu
    Builtin LCD should be 1440x900 External LCD should be 1920x1080 If X200s is inserted into docking station the option mirror screen is always activated leading to a resolution of 1152x864 which looks terrible on the builtin and external lcd. My manual configuration for docking mode (seperate screens with maximum resolution) should be respected, but "Make Default" button has no consequences. Found a quick fix, but this cant be the offical ubuntu way... /etc/udev/rules.d/99-vga.rules: SUBSYSTEM=="drm", ACTION=="change", RUN+="/usr/local/sbin/vga_changed.sh" /usr/local/sbin/vga_changed.sh: #!/bin/bash dmode="$(cat /sys/class/drm/card0-VGA-1/status)" export DISPLAY=:0.0 if [ "${dmode}" = disconnected ]; then /usr/bin/sudo -u kiu /usr/bin/xrandr --output LVDS1 --mode 1440x900 --pos 0x0 --output VGA1 --off elif [ "${dmode}" = connected ]; then /usr/bin/sudo -u kiu /usr/bin/xrandr --output LVDS1 --mode 1440x900 --pos 0x0 --output VGA1 --auto --mode 1920x1080 --right-of LVDS1 fi

  • Jumping Login Box after Lighdm Multiple Monitor workaround

    - by Tom Gamon
    So I used this workaround to sort my resolution at the login screen when using multiple monitors with Lightdm. #!/bin/bash XCOM0=`xrandr -q | grep 'VGA1 connected'` XCOM1=`xrandr --output LVDS1 --primary --auto --output VGA1 --auto --right-of LVDS1` XCOM2=`xrandr --output LVDS1 --primary --auto` # if the external monitor is connected, then we tell XRANDR to set up an extended desktop if [ -n "$XCOM0" ] || [ ! "$XCOM0" = "" ]; then echo $XCOM1 # if the external monitor is disconnected, then we tell XRANDR to output only to the laptop screen else echo $XCOM2 fi exit 0; Found Here: How to force Multiple Monitors correct resolutions for LightDM? It works great. However, now when I am on my login screen, the login box seems to jump to between the two displays. Any advice as to how I could make it stay on one display? Thanks

  • Serverless Web Application

    - by Andrea Di Persio
    In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

  • Attempting to install Ubuntu 11.10 along side Windows 7 Professional 64bit. Installer doesn't recognize an operating system present

    - by KichigaiDave
    System Details: Asus Sabertooth 990FX motherboard AMD FX-8120 CPU 16 GB DDR3 1600 Corsair Vengance RAM (4x4) EVGA Nvidia GTX-560Ti video card 2x Dvd/cd rw dirves 1 Bluray RW drive 1 Orico USB 3.0 & eSata panel 1 Sabrent floppy bay card reader w/USB 2.0 port 760W pc power & cooling PS OCZ agility 120GB SSD (Windows 7 Professional 64bit installed in an approx 80gb partition, NTFS. There is also a "System Reserved" partition shown in disk management at 100mb in size, also NTFS) That leaves about 32GB usable free, un-partitioned space in which I hoped to install Ubuntu. However when I run the Ubuntu 11.10 AMD64 installer, it doesn't show there is even an operating system installed. It just shows the entire drive as free-unpartitioned space. Just not sure what to do here. I was thinking about using the Wubi installer, but i don't know about that. Is the performance reduction pretty drastic? Thanks,

  • attempted WUBI install corrupted Vista

    - by oliver zimmermann
    Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!

  • UbuntuStudio 12.04 does not boot after install - no "intrd" image

    - by user72705
    After installing Ubuntu Studio 12.04 from DVD onto the fourth hard disk, it fails to boot, even when explicitly choosing the fourth hard disk as the boot device. I have SUSE 11.2 on the first 2 SCSI disks (which form a RAID) and Studio64 on the 1st IDE disk (that is, the third disk). Looking at the /boot directory on the Ubuntu partition, I see there is no initrd image. Editing the GRUB configuration file to include (hd3,1)/vmlinuz and of course (hd3,1)/initrd should fix the problem. But still GRUB gives a file not found error. This appears to me that, no mkintrd during the booting process (checked with LiveCD) runs like in OpenSUSE. How do I create the initrd to make Ubuntu bootable.

  • PC won't boot up after installing 11.10

    - by bakhshu
    I have a HP/Compaq s1010z (AMD64) desktop and installed 11.10 from a CD (using the entire disk). So it formatted the entire drive, went through installation and then it ejected the CD and asked me to click the Restart button, which I did. It rebooted fine the first time, but any time thereafter, it fails. Meaning, after the initial BIOS screen, the monitor seems to be stuck in limbo with a text cursor blinking on the top left corner, as if it can't find anything to boot from. At first I tried reinstalling (reformat entire drive again) - no improvement. Then I did an in-place re-installation (leave home dirs in place, just redo the OS), nothing there either. Then I put in the 11.04 CD, changed the boot order to CD first, and got the CD menu, chose 'Boot from first hard disk' and it booted fine. The problem is that I can't boot without the 11.04 CD, how ironic! Any ideas?

  • What's a good way to get an IT internship? [closed]

    - by user1419715
    I'm a second year CS student who's worked really hard to build and expand my skills. I've spent the past week now trying to find a place to volunteer (i.e. work for FREE) so I can get a little bit of in-the-door experience with web development. I have a portfolio with several decent projects, a handful of languages and other hard/soft skills that employers constantly say they're clamoring for. I can't even get people to take my calls. This is me offering to work for them for FREE, remember. I'm in a reputable program at a respected school, get decent grades and...yeah, I've worked really hard to be presentable. On the rare occassions I actually get to speak to somebody at a design firm they hedge and do everything they can to get me off the phone. Nobody's ever expressed even the slightest interest in taking me on. The answer to the experience problem is supposed to be "you need to spend a year or two building up a big portfolio of projects on your own" so that employers will be impressed. I've done that. Websites, standalone apps, etc.. Nobody will even look at my resume, though. Question: Why does there seem to be so little interest in taking on upaid interns in the world of IT? Update: Sorry you all think I'm too aggressive or angry. It wasn't my intent to be a jerk to people while asking them for their opinions. That said, how would you feel if employer after employer turned you down cold when you offered yourself to them without asking for remuneration? One can't even get an unpaid job in this economy now, it seems. How am I going about my search? I find web firms in my area and contact them via email with a brief sales pitch of myself and a resume attached. Then a couple of days later I follow up with a phone contact. Nobody--anywhere--is advertising for interns of any kind. If there were I'm sure there'd be about 500 resumes per position, even unpaid. I've had good experiences in the past with cold-calling firms for actual paid jobs in other industries (hiring is a pain in the ass process and a call like this can show initiative while reducing a busy employer's need to do all the hiring overhead work), so I thought volunteering would work at least as well. My skills are pretty good for a CS student and include the usual suspects: HTML/CSS/Javascript, Python, Java, C, C#/.Net etc etc. I made a point on my resume to tie each ability claim to a project as well. Oh, and regarding the "working for free still costs the employer money" argument: that's an excellent point I hadn't though of. But it means...what? I have to pay the employer for the privilege of working there now?
