Enter Safe Graphics Mode In Ubuntu Or Kubuntu 10.04 Lucid Lynx Live CD

Enter Safe Graphics Mode In Ubuntu Or Kubuntu 10.04 Lucid Lynx Live CD

So you downloaded the handy-dandy Kubuntu Live CD to play around with. YEY! But for some reason it won’t display any graphics on your monitor. You might get: pixelated images, distorted views, a blank screen or even a blinking LCD power button. Oh yey … kinda screwed there because you can’t even get INTO the boot cd in-order to maybe change the video settings or install updated drivers.

Fear not! There is a solution … or two!

Many of you know of the wonderful “F4″ options screen on the boot CD. After you boot to the CD and it asks you for your language selection, and you select whatever … you are presented with several main options like “Try Kubuntu now”, “Install Kubuntu” … blah blah blah.

All those failed to actually work! So here is what you can do. On that screen, simply press the function key: F4. This brings up a alternate boot options menu. You’ll be presented with stuff like:

  • Normal
  • Safe Graphics Mode
  • Use driver update disc
  • OEM Install

Simply select Safe Graphics Mode and *poof* you’ll (most likely) enter the awesome works of linux :).

BUT WAIT! I DON’T SEE A “SAFE GRAPHICS MODE” OPTION! Oh noes!

No problem actually :)

This (sadly) happens on the x64 versions (at least the ones I have tried). So what to do? Just follow the steps below and you’ll be in Safe graphics mode!

  1. Press F6 to open the other options menu.
  2. This opens this new menu … it’s useless to us. So now close it!
  3. We did this so that the command options show up near the bottom of the screen. Press tab to access these options.
  4. Press space one (to make some space) and enter the following:     –xforcevesa
  5. Press enter to boot

That options forces “safe graphics mode”, which essentially is forcing the graphics drivers to be a software driver. Ie: you’re CPU will do all the heavy lifting.

With that option will you safely be able to try out Kubuntu (or even Ubuntu) Linux! Of course you won’t have the prettiest graphics, but at least it will work!

I got this information from this link, it saved me a huge headache: http://www.overclock.net/linux-unix/732545-how-install-ubuntu-10-04-ati.html

Trine 2 Ubuntu Linux Audio Stuttering & Pop Sound Workaround

I love Trine 2 as much as the next guy, though technologically speaking there are some issues. Just check the forums and you’ll know what I mean. Thankfully though I only came across one issue, and that’s where when playing, no matter what resolution or graphics settings, there is always serious lag in some areas and the audio constantly stutters, pops and lags. It really sucks since that makes it barely playable, actually after about 10 minutes it’s completely unplayable.

So what could be the issue? Well, it’s not as simple as we thought. Let’s take a look at why this happens first, then I’ll give you the solution.

[SOLVED] Creative X-FI Titanium (ctxfi) on Ubuntu 11.10

The Creative line of cards can be a handful at times, so that’s why we (by we I mean other Linux developers) developed Alsa and open source drivers. Contrary to popular belief, you do not need the official drivers from Creative. All you need is a little bit of time and command-line work. For this,

The Creative X-FI Titanium card has, for a long time, not worked on Ubuntu … until now. I’ve gathered what information I could and found a solution to get it working 100% of the time. This doesn’t mean it works to 100% of it’s potential; some features are still missing such as the Crystalizer and fun features like that. Though it does record audio well, processes extremely well and with my help you’ll have it blasting at full 5.1 digital goodness.

  • Safemode VGA= 771 Alternative

    Thanks for the great hint! Your method did not work for Ubuntu 10.04.1 LTS installation on my old Dell Latitude C400. I just wanted to share that adding: vga=771 instead of: -xforcevesa in your step #4 did the trick. It triggers an 800×600 VGA display mode, compatible with most monitors.

    In my case, neither vga=771 or -xforcevesa would allow me to run the live disk of Ubuntu 10.10 or even boot to an installation successfully installed from the text based “alternative” Ubuntu installation disk. I can now upgrade easily from 10.04 to 10.10, if I so choose. Thanks for getting me on the right track, and I hope my suggestion can help someone else!
