*** This bug is a security vulnerability ***
Public security bug reported:
I have a 42'' LCD TV and when I boot up Ubuntu 9.10 and below (8.04-9.10) the
screen is always shifted because Ubuntu does not recognize the correct
resolution of my LCD TV. Then, I connected my computer to my spare 20'' LCD
monitor and everything works perfectly and the screen image is centered with no
need for me to adjust the screen resolution.
In Ubuntu 10.04(both alpha and beta versions), when I boot up with my 42'' LCD
TV the monitor says "no signal" and then shuts off. I then connected my
computer to that same spare 20'' LCD monitor, rebooted ubuntu 10.04, and
everything worked perfectly. (I believe the fact that 10.04 does not work at
all with the LCD TV has something to do with noveau being used by default
instead of the nvidia driver because I have the same problem with Fedora (which
uses noveau by default) but no problem with Opensuse or windows)
Many people have reported the same "no signal" bug with LCD TV's booting ubuntu
that I have run in to in the tech support forums. I just never realized this
problem was due to Ubuntu running on an LCD TV (32"+) instead of running on an
LCD computer monitor (20"). Please let me know if you have any questions
because Ubuntu rocks and I want to help them get rid of these bugs. Thanks -
Adam
(I'm not sure if this qualifies as a security vulnerability but I
suppose not having acess to the Ubuntu OS could be a security
vulnerability, so I will check the security box and I apologize if this
was an incorrect assumption)
