• install 64 bit as dual boot with 32 bit

  - by profgeorgefhart

  I downloaded Ubuntu 12.10 - bit .iso onto a bootable USB and want to put it on to my 32 bit 12.10 system as a dual boot, using a totally separate 1 Tb disk [which already has data on it]. However, when I go to restart and hit F8 fir BIOS set-up, I can change all the settings except the boot search order. Is there some other way to force the startup to read the USB first? Is the fact that I cannot change the search order to do with the fact that the 32 bit OS was 'Installed in legacy mode' not 'EFI? How can I rectify this? (This might be related -- might I need to update my BIOS for my Intel DX38BT motherboard? I think their last upgrade was 2009.)

• Can't restart from Ubuntu 12.10

  - by Sankalp Kota

  I am dual-booting Ubuntu 12.10 and Windows 8 Pro. Both run seamlessly but I've had the persistent issue of not being able to restart my machine properly from Ubuntu. If I am on Ubuntu and hit the 'Restart..' option, the screen turns off and Ubuntu shuts down, but the computer never turns off and grub bootloader never shows on the screen. However, rebooting from Windows gets me to the bootloader as it should. Turning off the machine completely with 'Shut down' works fine with both Ubuntu and Windows as well. This issue was present even when I was dual booting Ubuntu 12.04 and Windows 7 Starter as well. My computer is an Acer AOD257 with 2 GB RAM, Intel Atom N570 Processor. Any help would be greatly appreciated!

• Dual screens with one workspace on each?

  - by user2413

  Hi all, I have a dual screen, compiz-fusion and i don't have a NVDIA/ATI graphic card and i use ubuntu 10.10. i currently use the two monitors: the desktop is stretched across monitors and i can drag an application across monitors. My question follows: i would like to use the left monitor only to display workspace1 and the right monitor to display workspace2. Is this possible ? If yes how (I've found mention of dualXscreen on this board, but i can't find it in the compizConfig menus). Best,

• low volume/dual boot

  - by user2367

  I have an intel Imac dual-booting Ubuntu 10.04 and OSX 10.6. Both work fine, but sound is very quiet in Linux, even though the gnome volume control panel and pulse audio volume control panels are both set to 100%. I can turn the speaker volume up and it's fine, but then when I boot back to OSX the volume makes me jump out of my skin. Is there a setting I'm missing? If I turn the gnome sound pref volume higher then 100, it tends to distort the sound. (crackling)

• Can Tutorial "Dual Boot Windows 7 & Ubuntu 12.04" Used for Dual Booting Windows 8 & Ubuntu 12.10?

  - by Shyuan

  I previously used this tutorial to dual boot Windows 7 and Ubuntu 12.04 perfectly. Now I have upgraded my Windows 7 to Windows 8. And I would like to do a fresh install (and start all over again like the tutorial) of Ubuntu 12.10 replacing existing Ubuntu 12.04. I like the way the tutorial presents thus can anyone kindly let me know if the tutorial is compatible with what I wanna do now? I have tried doing little research whether this has been asked, but all I got are not too similar to my question, if there are topics like this I do apologise and feel free to close it. Hope to hear from the community. Thank you so much. :)

• Convert to WAN port

  - by Ramon Marco Navarro

  I have a ADSL2+ Modem/Router. Is it possible to set one out of four of the LAN ports as a WAN port? If yes, how? The brand/model is: Prolink H9200P. I already contacted Prolink about this and the site said to wait for one business day. But I'm still asking here just in case someone could answer faster than Prolink. Thank you.

• Cisco RVS4000: multi-WAN support?

  - by gravyface

  Can anyone confirm if the RVS4000 has multi-WAN and policy routing support? Manual doesn't really say yes or no, I'm thinking no, knowing Cisco but want to confirm before I recommend another firewall.

• Cisco SR520w FE - WAN Port Stops Working

  - by Mike Hanley

  I have setup a Cisco SR520W and everything appears to be working. After about 1-2 days, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device. If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my Comcast Cable Modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again. Any ideas?

• (Zywall USG 300) NAT bypassed when accessing in-house-server From LAN Via domain name

  - by mschr

  My situations is like this; i host a number of websites from within our joint network solution. On the network is basically 3 categories: the known public, registered via mac, given static dhcp lease the anonymous lan connections, given lease from specific dhcp range switches, unix hosts firewall Now, consider following hosts which are of interest 111.111.111.111 (Zywall USG 300 WAN) 192.168.1.1 (ZyWall USG 300 LAN) load balances and bw monitors plus handles NAT 192.168.1.2 (Linux www) serves mydomain1.tld and mydomain2.tld 192.168.123.123 (Random LAN client) accesses mydomain1.tld from LAN 23.234.12.253 (Random External client) accesses mydomain1.tld via WAN DNS A records are setup so that both mydomain1.tld and mydomain2.tld points to 111.111.111.111 - and the Linux www serves the http parts with VirtualHost configurations, setting up the document roots pr ServerName, this is not so interesting though.. NAT rule translates 111.111.111.111:80 to 192.168.1.2:80 (1:1 NAT) Our problem follows; When accessing http://mydomain1.tld from outside (23.234.12.253 example host) the joint network - everything is fine, zywall receives requests via port 80 and maps it to the linux host' httpd. However - once trying to go through the NAT from LAN side (in-house, 192.168.123.123 example host) then one gets filtered in the Zywall port 80 firewall. I know this only because port 443 is open for administration interface and https://mydomain1.tld prompts for zywall login. So my conclusion is, that the LAN that accesses 111.111.111.111 in fact are routed to 192.168.1.1 whilst bypassing the NAT table. I need to know how to setup NAT / Policy Route, so that LAN WAN LAN will function with proper network translations instead of doing the 'quick nameserver lookup' or whatever this might be.

• License Requirements for Including Dual-Licensed Open-Source Software

  - by Rick Roth

  How do you opt into one software license and not the other when the distributor gives the consumer more than one choice? For example I would like to use the DataTables JavaScript library in my web application. According to their web site, "DataTables is dual licensed under the GPL v2 license or a BSD (3-point) license." Furthermore, the source code of the JavaScript library has this text that calls out both licenses: /** * @summary DataTables * @description Paginate, search and sort HTML tables * @version 1.9.4 * @file jquery.dataTables.js * @author Allan Jardine (www.sprymedia.co.uk) * @contact www.sprymedia.co.uk/contact * * @copyright Copyright 2008-2012 Allan Jardine, all rights reserved. * * This source file is free software, under either the GPL v2 license or a * BSD style license, available at: * http://datatables.net/license_gpl2 * http://datatables.net/license_bsd * * This source file is distributed in the hope that it will be useful, but * WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY * or FITNESS FOR A PARTICULAR PURPOSE. See the license files for details. * * For details please refer to: http://www.datatables.net */ Finally, the web pages with the licensing text (e.g. the DataTables BSD license page) has this statement: "DataTables is made available under both the GPL v2 license and a BSD (3-point) style license. You can select which one you wish to use the DataTables code under." My specific question is "how do you select which one you want to use." In my case, I want to only use the BSD license and I want to make it explicitly clear that I do not opt into the GPL v2 license in any way. How do you do that and have it hold up to legal challenge?

• wine 1.4 regedit makes screen flicker on 12.04 with dual monitor setup

  - by s1lv3r

  I have a dualmonitor setup running dual 23" on 1920x1080 which has the following problem: When running any wine application (for example "wine regedit" from console) the screen flickers and the windows have artifacts like this: Also sometimes taking a screenshot using the print key will make compiz crash (starter and all window bars/menus are gone) when an wine application is started. I don't have the same problems on my notebook which has the same setup. Only difference is the notebook has ATI Graphics and this PC has nvidia. This is the output of lshw -c video: *-display Beschreibung: VGA compatible controller Produkt: G72 [GeForce 7300 LE] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:07:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nvidia latency=0 Ressourcen: irq:16 memory:fa000000-faffffff memory:d0000000-dfffffff memory:fb000000-fbffffff memory:fce00000-fce1ffff I also noticed that running xrandr from console makes the screen flicker for some seconds on this PC, which also doesn't happen on my notebook. Removing one screen from the setup will stop the flickering and the artifacts inside the wine applications from appearing. Does anybody have an advice what I could try to change to make this work?

• Dual monitors, screen resolution, xorg.conf.d

  - by Flase

  I do a lot of RTFM but this one has got me stuck. I have Ubuntu Studio 12.04 Precise Pangolin with XFCE as its default desktop. My old HIS ATI Radeon 9250 graphics card was adding red crud across the screen with the generic driver, but downloading the proprietary "fglrx" driver makes it work cleanly. The trouble is the Catalyst control centre refuses to recognise my old card so I must do some manual configuring to make sure both the DVI and VGA monitors are capable of the correct screen resolution (both 1280x1024) and a dual display. It used to be easier to just edit the existing xorg.conf file and add another resolution and so forth, but now there are automatic xorg.conf.d directories (more than one) with scant documentation. Creating a generic xorg.conf with a terminal command creates every setting imaginable. What I want to do is create the simplest conf file which just tells the system the following: My VGA monitor can do 1280x1024 60Hz The two monitors together may be 2560x1024 width The VGA monitor on the right I might need to specify Xinerama if it's needed Thank you. I don't think I need to bore you with log files, but please ask for further info. Mike

• HP Pavilion 15 with AMD dual graphics - Ubuntu live environment not starting

  - by creepus

  I've had this laptop for about a day now and have decided to try Ubuntu on it and determine if I want to install it. I created a USB, it booted (Secure Boot was on, I tried with Secure Boot off to no effect), and then the problem occurred. The screen turned off for a second, turned back on to a black screen, shut off again and turned back on with a dialogue box telling me that the system had to use low-graphics mode. I clicked OK, selected low-graphics mode from the menu and clicked OK. The screen switched to the boot messages and did not go any further than this. Ctrl+Alt+DEL started rebooting the laptop though. I tried booting again, but this time I edited the boot options in GRUB to add nomodeset. This time, the laptop only booted to a black screen. Ctrl+Alt+F2 took me to a prompt, I tried startx from there, but X didn't start, complaining that it wanted kernel mode setting back. I can not seem to find any option to disable one graphics chip or the other in the UEFI setup menus. Laptop : HP Pavilion 15-E004AU. The CPU : AMD A6-4400M APU with Radeon(tm) HD Graphics The graphics chip : AMD Radeon HD 7520G + 8670M Dual Graphics. The Ubuntu version : 13.10, 64 bit. Thanks. EDIT: I tried 12.04.3 LTS, it managed to bring the desktop up. There are severe graphics glitches after about two minutes though.

• dual monitors and unity - ati radeon cards

  - by michiel

  I have a vaio laptop with an ATI Radeon video card and an external screen. I used to run dual monitors on Ubuntu 10.10 fine, but recently decided to upgrade to 11.10 via 11.04 I don't think it's the video card or the fglrx driver. It seems to be unity. When I start up, the laptop screen is normal and the external screen is all white, although I can move my mouse over it. However, the cursor becomes the big X that used to be cursor of the first versions of Xwindows. I can right click on it, and it brings up the context menu for the desktop. And then, all of a sudden, it shows my desktop background. I can continue to move my mouse over the external screen, and now the cursor is normal (little white arrow). But I can't do anything any longer (not even the context menu as before), and trying to drag a window to it (which always worked on 10.10) doesn't work. I actually really like unity. It gives me the most our of my desktop, and uses all space available, which is great. But how can I get my second screen back? I tried unity 2D, but the result is the same. Edit: I think I stumbled on this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143

• Install Mac OS Lion on Macbook with existing Ubuntu 12.04 dual boot

  - by kash

  I don't usually create my own questions, because I can find what I need through other people's questions. However, this one doesn't seem to be anywhere, except in one place where someone is talking about not using Apple hardware. So here it goes. I am using Apple hardware. I have a MacBook 1,1 with Intel Core2Duo running Ubuntu Precise Pangolin flawlessly. I never considered starting with Mac OSx and dual-booting because I never liked Mac OS. Now that I'm realizing that the only way I'm going to be able to run my DAW (Reaper) nicely and use a Firewire recording interface is to run Mac OSx, I'm considering it again. I want to go the opposite direction of most people and install Mac OSx next to an existing Ubuntu installation and have a boot menu with refit. I've installed refit in Ubuntu and I've converted the .dmg file for Mac OS Lion to a .iso file. Now, should I mount the .iso in Ubuntu and run it there, or burn a DVD and restart? I'm trying to gauge how to do this without hurting my existing Ubuntu installation. I will of course keep looking for existing answers in the meantime.

• ATI Radeon 5800 series dual monitor unity not 3D accelerated

  - by Victor S

  When I had a single monitor setup, without Xinerama, with my current setup of Ubuntu 11.10, ATI 5800 series card, Unity showed transparencies, shadows, etc. (although graphics was reported as 'Standard' in the control/settings panel). Having switched to a dual monitor setup, dell 24" UltraSharp and a smaller Acer monitor, Unity shows only as 2d, even though I'm not loggin in to that display manager. WebGL performance is very sluggish, I'm getting the impression that the processor is doing all the work and the card isn't even accessible even though the drivers are installed (from the ubuntu repository, I did not compile custom drivers). Any tips on how to enable full 3D accelerationn and video card support.

• Dual Monitor 'How To' for 12.04

  - by Kim Prince

  I recently built my own PC and was delighted with the result, except for a problem with dual monitors. After having tried a few different combinations of hardware, I think what I really need is a 'how to' explanation. My motherboard is an MSI Z77MA-G45, which has an analogue, a DVI, and a HDMI port. Initially I hooked monitors up to the DVI and analogue port and it seemed to work fine. Both screens worked independently of each other, it was great. After a few days I started turning my PC off at night, and when I tried to turn it back on it would boot into the terminal mode. I would have to turn one of the monitors off and after rebooting a few times, it would eventually boot into an X Window session. Occasionally I would see an error relating to Xorg. I upgraded the motherboard BIOS but that made no difference. Eventually, I installed a graphics card - an NVIDIA GeForce GT 520. Now it seems that my on board graphics have been disabled completely, and I am reliant on the graphics card. Furthermore, the graphics card seems to only recognise one screen at a time. (The first time I rebooted with both plugged in, it flashed up a message saying that it was auto-selecting DVI). Anyhow, I think I need some 'how to' (or perhaps 'where to'), from here. For example, is X Windows configuration the next place to look? And how do I go about configuring X Windows? (Note that in Systems Settings it says my graphics driver is 'unknown', and when I ask it to detect monitors, it sees only the one!)

• Ubuntu Unity (64-bit) Bugs on Nvidia dual screen [closed]

  - by Kristofer

  On my work computer I have upgraded 10.04 to 10.10 and now to 11.04. Upgrades have mostly worked well and the dual screen setup is almost working. There are however a couple of annoying bugs which I tried to report but the bug reporting tool told me to ask about the bugs here. Here's what I have found: Auto-hide stops working. It doesn't seem to matter which application is maximised/covering the dock, it just stays on top. I have tested changing the autohide settings with no result. Scenario: One maximised window on each screen. If I now try to drag the window that doesn't have focus by dragging the top of the window nothing happens. I can also not give the window focus by clicking the top bar, I have to click inside the window and then I can drag the window. If I unmaximise the window with focus it does work and I can both change focus and drag the window directly by clicking the top of the maximised window. Any bug fixes coming for these issues? Any work-arounds?

• Xorg crashes ever since using Nvidia dual monitors

  Well ever since I have used dual monitors with the NVIDIA X Server Settings program my xorg process has been crashing after a while, and its generally a pretty long while of like 6 hours afterwards.

• Accidentally Changed Dual Monitor Setup and don't know how to reset it

  - by user203783

  I have a dual monitor setup with my laptop and an external Asus monitor running under Ubuntu 11.10. When I first started using Ubuntu, it synced both screens. What showed up on my laptop showed up on my eternal monitor. Last night, I accidentally knocked the HDMI cable from its port (not that unusual in the tight space I work in). When I plugged it back in, as usual, the external monitor only displayed my wallpaper. Usually, I just restart Ubuntu and it resets, but last night what I now realize was the display console came up and somehow I changed the setup. Now the two screens show different jobs so to speak. Also, the external monitor doesn't display the ribbon, making switching between Firefox tabs and windows or apps jarring. I write for a living and need to quickly check bits of research, notes or sources while writing and the extra switching between mouse pad and external mouse to get one or the other screen to respond interrupts my work flow. The only technical help I can offer is when the display console popped up, the graphical representation of the screens was that the external screen appeared layered over by about one-quarter of the laptop screen. Again, these were icons. I tried to replicate that after I obviously screwed things up. If someone could help. I would appreciate it. If I have to use terminal, that's fine. I started using computers for writing back when they were green DOS prompts. There's a certain elegance to prompt commands to me. Maybe it's the writer in me. Again, if anyone can help me return my screens to sync under Ubuntu 11.10, I would greatly appreciate it.

• Problems with dual monitor & resolutions, only in 14.04

  - by theLadder

  I installed Ubuntu 14.04 but i am having weird problems with my dual monitors and the resolutions. I also tried Xubuntu 14.04 and was having the same problem. I have one 32 inch LG TV with 1920x1080 and one monitor with 1280x1024 resolution. When i first start my 32 inch gets 1360x768, if i then try to change to 1920x1080, everythings looks fine and the prompt asking me if i want to keep settings comes up and starts the countdown, but after 2 seconds my computer freezes, and after a few more seconds it reboots itself. However, if i disable my smaller monitor first, i can change to 1920x1080 on my 32 inch without problems, but if i then activate the second monitor the same problem happens again. in Xubuntu 14.04 i can change the refresh rate, if i run the 32 inch at 30hz or 50hz everytying works, but i would like to be able to run it at 60hz. I'm currently running Xubuntu 13.10 without this problem. My graphics card is a ATI Radeon HD 4850. What is causing this problem, grahpics drivers? Kernel? Xorg? And how do i solve it?
