Overscan,Blackscreen, garbage on screen

We havent pinned it down yet people but I believe by default Hardy tries to use a 800x600 75hz setting for video. I also have had this issue and it mainly affects ppl with a LCD screen. For those that do not know LCD's generally like 50-60hz on refresh rates, anything higher and you get the black screen, garbage on screen or a overscan msg on your monitors. Most LCD's will support a range of resolutions depending on make and size but they always have a NATIVE resolution, The one that there made for and will look the best by far.
I found for me when I install I have to get to the menu hit F6 and add a noacpi on the end of the Kernal modifier line. I then boot using recovery (second choice) and sometimes I also have to use the F4 option and select a generic monitor and VGA card and set the Resolution etc. Then once I'm in desktop ( I might add it took me 5 trys one time to find ones that worked ) I can use Envy in 1.7 or EnvyNG on the 1.8 and install the video drivers. Once I VERIFY they are set and the default I can then reboot and go about life without a hitch. ANYTIME YOU MODIFY THE KERNAL you generally have to reinstall them. One last thing I am just guessing at the default resolution and refresh but I have seen a TON of post on this. I hope this helps and if any Admins or Mods care to edit this post with better details feel free too. I am just posting what has worked for me and a few others I have helped.

I have noticed that I can not have the nvidia drivers enabled and get video through my DVI connection in 1.8. This worked for me in 1.7. Both versions are 64bit.

Any ideas if this may be related.

That was also my case I also use a DVI cable. Once you get it set seems to be perfect I wont bore everyone with the details but they made a change in the xserver-xorg and well its been a pain. We can usually get everyone working but I sure wish they would make it more "newbie " friendly. Thats not ment as a insult to anyone but my concern is Ubuntu especially Ultimate edition is a GREAT OS and if you can get someone in the door and see how nice it is they are usually hooked and the community grows. This blank screen etc thing and the wireless issues are just a pain to deal with. I can understand when a specific piece of hardware has an issue like lightscribe etc. but general devices like monitors and keyboards etc.. should work without all this effort. Thats my 2 cents I dont speak for everyone here tho.

You are right Cab..seems like Hardy is trying to eliminate the need to reinstall drivers for video after a kernel update..trying to do it in one download..problem arising is they messed with the xserver-xorg system of manual configuration...hope it will be resolved shortly..this is a problem people are having.. :|

I have issues with Ultimate Edition 1.8 as well noacpi was not necessary for me, the screen blacks out on occasion, I wait for it to come back on and continue until I can get it installed, once it is installed same situation continues until I can get envy to go through, I assumed this to be because I have 2 ATI cards installed (unsupported in linux period), and was switching between them, I also run widescreen lcd. Never even thought of that, If I get the chance will rip one out and test your theory.

Maddog, has installed the 32 bit edition get this installing while using compiz wobbly windows(compiz), I did not inject ATI drivers, I was shocked, note the live session at the top...

If I get time I am thinking about reinstalling 1.8 using my 19"crt to see what the default resolution and refresh rate is. I want EVERYONE to know this is not a ULTIMATE EDITION problem it effects all using the HARDY release. When I say all I mean within the parameters seems to be a nvidia and widescreen thing. I wont even chime in on getting ATI cards working properly.

I always feel the need to say I like ATI and Nvidia I've owned em both, When *nix gets crossfire going nvidia better step up because I believe that will even the playing field if not shame nvidia. Time will tell as always.

Don't know if this is part of what ya'll are looking for in narrowing this down, but on my integrated nVidia 6150LE chipset and Dell E173FP LCD 19" monitor, during install it came up at 800x600 in both 1.8 & 1.7, and 8.04. However, I have not had any problems installing Envy drivers. Just thinking along the lines if it's more the newer cards/chipsets having problems.

Hi, like I said in another post I'm having the same problem. But before I decided to install Ultimate I tried Ubuntu 8.04 32-bit in Vmware, and I didn't have the black screen with mouse pointer once booted. How is that possible?

Kid regards, Tamara

Tamara .. my guess is that you did not load the Nvidia drivers in the VMware image. I can run just fine as long as I so not enable the Nvidia drivers... but what fun is that ?? :D

Hey Cab... do you have the DVI + Nvidia setup working? if so .. could you post your xorg.conf?

It worked fine for me the first time with 1.7 64bit and from what I recall, the .conf file was different from what I am seeing now.
