• Will 3D games run in a VirtualBox4-hosted Windows system under Ubuntu with Intel GMA X4500HD card?

  - by Ivan

  I've just got a laptop with Intel GMA X4500HD card (which is said to be DirectX10-compliant, while my previous laptop had Intel 82852/855GM and no chance to play modern 3D games at all). It would be nice if I could play some games (like HalfLife 2, StarCraft 2, Fallout 3) from time to time (while I am ok using lo-fi settings and having low performance) but as I strongly prefer Ubuntu environment and don't need Windows usually I'd like to install Windows inside VirtualBox instead of using a dedicated partition and dual-boot. So the question is if VirtualBox can use 3D acceleration of Intel GMA X4500HD if run on Ubuntu.

• Computer crashing after a few minutes of logging in

  - by user88612

  I have a fresh install of 12.04.1 on my machine. It is constantly crashing after logging in. I noticed it crashed repeatedly when using Minitube and would crash in Chrome. It seems to be that anything graphics related is causing it? I've booted the system 7 times and each time it would crash within 5-10 minutes after logging in. I have no swap and it's a dual-boot system with Windows 7. My system specs: AMD Phenom XII 925 8GB DDR3 (new) AMD Radeon HD 7770 GPU (new) Seagate 1TB Barracuda HDD (new) Catalyst Drivers

• What IRC client(s) would allow me to filter out log messages?

  - by Aras

  I have been using Empathy and more recently Pidgin as my IRC client. But there is one feature missing from both of these clients that keeps bothering me. I want to be able to see only what people are actually talking about in each channel. I often like to leave IRC channels open and go back to them and read the messages for the last few hours or days. I saw that IRC clients have been discussed in this post and a few others, but I have not found what I am looking for yet. Here is what I want to see in my IRC client: what actual people say Here is what I do not want to see message about people entering the room people leaving room people changing their status messages or what they are known as people sneezing people's cats sneezing Anyway, you get the picture. What IRC clients are available for Ubuntu that would allow me to configure what I see so that I can see what people are talking about -- and nothing else?

• Screen sometimes inverts after locking

  - by hackedd

  Sometimes, when I wake up my computer from a screen lock, one of my screens is inverted. It does not always happen (maybe one in ten times) and it is not always the same screen. Re-locking and unlocking the screen a couple of times fixes the colors again. I have a dual monitor setup on an ATI Radeon HD 3450, using two HP screens connected over DVI. I am using the radeon driver, and according to jockey there are no additional drivers available for my system. Any ideas as to why this happens?

• Upgraded to Ubuntu 12.04--keyboard & mouse no longer work--system down!

  - by Mackey Morgan

  I upgraded from Ubuntu 11 to 12.04, today, and everything seemed to go smoothly up to, and including the reboot. However, I now find that my mouse and keyboard no longer function, so I cannot login or otherwise use my computer. I have read other posts on this topic, but most of the answers seem to require the use of a keyboard to implement the solution--and I can't use my keyboard! I downloaded a 12.04 LiveCD and tried booting from it, but I have the same issue with that--no keyboard! My systems is a Lenovo with an AMD64 dual processor, and my keyboard and mouse are USB attached and shared with two other Windows PCs via a KVM switch (so I no the keyboard and mouse work!). I would appreciate some hints about how to make this PC usable, again. Thanks!

• unable to boot from live USB!

  - by ramblinman

  Linux noob here. I was messing around with my new dual-boot (win7 and the latest ubuntu, 12.04 I think?) Long story short, I deleted some partitions that I shouldn't have. When I boot up the machine, I get: error: no such partition. grub rescue _ I know that I could probably fix this by booting from the live USB. But I can't boot from the live USB either! On startup, I can get "boot from drive" options by pressing F12. (This is how I installed Ubuntu in the first place.) But when I select the USB drive, I get this error: error: no such device: [long string of letters and numbers]. grub rescue _ I've searched around for a fix but most threads addressing the first problem suggest booting from live drive. And I can't do that! Any help much appreciated.

• How to re-partition?

  - by EDi

  I switched from Windows to Ubuntu 4 months ago and I am really happy with it. I set up a dual-boot system (since I wasn´t sure how it will end up with me and Ubuntu). After merging from Citavi to Zotero I need windows only for my scanner. The problem I have now is, that the windows partion is so big with lots of unused space and the ubuntu partition are quite small - I should have though about this problem 4 months ago... My partitions look like this: Where sda3 is the windows partition, sda5 is Ubuntu and sda7 is a data partition. I want to shrink sda3 and free some space for sda5 and sda3. How can this be done safely (and easily)?

• How do I access an external hard drive plugged into my router?

  - by Shawn

  I am running Ubuntu 11.10 and I own a Netgear N600 Wireless Dual Band Router with a USB port built into it. Naturally, the router came with instructions on how to mount and view this drive with both Windows and Mac, but nothing about Linux. I have an WD Elements 1 TB external HDD that I would like to plug into the router and share across my home network. However, when I plug it in, absolutely nothing happens on my desktop. I checked on two different machines and nothing seems to indicate that the drive has been mounted (or is even seen at all) on either machine. I am fully aware that it may not be possible to do this with a Linux system, but I was hoping someone might have a suggestion. Thanks!

• Usb/vga not recognized anymore

  - by Peter Raeves

  I don't know what happened, but yesterday everything worked fine, but when I woke up this morning and booted my computer to Ubuntu 14.04 a bunch of hardware isn't recognized anymore. I use a dual monitor setup with dvi-d and vga, but the vga screen isn't recognized anymore and the dvi-d monitor is recognized as "Built-in Display" while I'm not on a laptop. Also every device connected through usb isn't recognized anymore either. I have a keyboard with the blue round connector, which still works, so I can still log in though. The computer goes slower than usual and I have no idea what has happened. Can anybody point me in the direction I should start looking, because this is scary! I just checked and both the front and back sound connectors stopped working also :/ Edit: The devices connected through USB are recognized as they all show up using sudo lsusb, Ubuntu just doesn't let me use them anymore.

• How to implement custom texture formats in Android?

  - by random1337

  What I know: Android can load PNG, BMP, WEBP,... via BitmapFactory. What I want to achive: Load my own 2D file format (e.g. 1-bit texture with a 1-bit alpha channel) and output a RGBA8888 texture. Question: Is there any interface to achieve this?(or any other way) The resulting image is used as a texture for a 3D model. Why would you do that? Saving phone memory and download bandwidth while expanding the texture at runtime to RAM seems reasonable for very simple textures.

• All files erased after installing ubuntu 11.04 alpha 3

  - by wifi

  Yeah I know I should have backed up my files before proceeding, I completely forgot. Well, the thing is that I had a dual-boot system with Windows 7 and Ubuntu 10.10. Yesterday, I installed Ubuntu 11.04 alpha 3 (through live USB). I chose that 11.04 would install over 10.10 on the installation wizard, where I have no important files. However, it overwrote Windows too, and its data. Is there some way to recover it? Thanks!

• compiz problems - no effects work, despite the fact that they seem to be properly configured

  - by user97551

  I've looked through some posts about compiz and either haven't found the answer, or haven't understood what's been said. Could someone help me out? I installed ubuntu 12.04 through windows 7 (so I can dual boot) and installed compiz and set up the settings I want (hotcorners etc). For a while it seemed like it was going fine, but then I restarted the laptop, none of the compiz settings were working and the auto-launcher wasn't even coming up when I passed cursor over it. The computer is still usable, when I 'dash home' the auto-launcher appears, and I can tab through windows but yeh... the auto-launcher and hotcorners I set up through compiz aren't working at all. Any ideas? Oh, whilst I'm super grateful for any help I can get, I'd really appreciate it if you could keep any instructions as basic as possible. I'm a bit new at this... THANK YOU!

  I have a Iomega Home Media Network Drive Cloud Edition 1TB that started clicking and then displayed a failure LED code Power LED and Red LED. I removed the SATA drive and inserted in a 'All in 1 HDD Docking Station' and connected to laptop by USB - Laptop has Win 7 OS. The dock is seen as drive E but cannot access and says 0% data etc. The drive does spin up when I power the dock. Web searches say the drive has EXT3 file system and to use Ubuntu to access drive. I have now setup a dual boot laptop but still do not see the drive using ubuntu. Is there something else I need to do to get it recognised etc. I really would like to recover the data, any suggestions please?

• 3TB non-boot hard disk on older motherboard

  - by Bcos

  It is time to expand the capacity of my Ubuntu home file server so I would like to purchase some 3TB hard disks. However, I am concerned with potential compatibility issues. I've tried searching around but I haven't found information which clearly addresses my particular situation. My server is running Ubuntu 10.04 on an Intel P35 chipset based system. The motherboard does not support UEFI (and, by extension, GPT?). However, Ubuntu does support 2TB disks. Will I be able to properly utilize these new disks, or does the motherboard limitation trump all else? The boot disk is <2TB and will not be updated nor am I dual-booting; these disks will be used strictly as slaves in a pure Ubuntu environment. I'd hate to pull the trigger on these new disks just to be unpleasantly surprised, so any feedback is appreciated. Thanks!

• Installing Ubuntu before or after upgrading from Vista to Win 7?

  - by amh

  I just got a new SSD hard drive for my thinkpad laptop. I just installed Vista with the factory CDs. On my old OS, my main OS was Ubuntu but I do want to keep Windows on a separate partition as a dual booth system. I definitely want to upgrade to Win 7 though and I will get it in a few days. My question is: should I install Ubuntu now and then upgrade to Win 7 in a few days? or is that going to mess up with the grub (or something else)? If that is the case, then I'd rather wait to install Ubuntu until after I upgrade to Vista. P.S. I know that probably any kind of mess done by the Win upgrade could be fixed, but I just want to avoid wasting time.

• Ubuntu 12.04 wireless detected, but can't connect to 128-bit WEP enabled microsoft MS-700 base station

  - by ubuntufan

  I installed Ubuntu 12.04 on a Presario R 3000. The Wireless card was not detected (firmware missing). Based on several related posts, I downloaded and installed the b43 driver and wireless was finally enabled. However, I am unable to connect to my base station successfully. The base station is configured for WEP 128-bit. I tried both infrastructure mode and ad-hoc mode (with the channel, band, etc. configured). Appreciate any help in trying to get past this.
