Try

lspci -vv

If you don't see a VGA card/chip on the list, then that's a bad thing, but I think you will.

To see your loaded kernel modules (drivers) do

lsmod

Re: screen goes black with no signal after update?

it says:
latency :0, cache line size: 32 bytes
interrupt: pin A routed to IRQ 16
(then lists the regions 1-5)

firewire (ieee 1394): agrere systems fw322/323 (rev 70) (prog-if 10)
susystem: asustek computer inc. device 8294
control: I/0 mem+ busmaster+ speccycle- memwinv+ VGAsnoop- parerr- step
ping - serr- fastb2b- disintx-
status: cap+ 66mhz udf- fasrb2b+ parerr- devsel=medium >tabort- <tabort-
<maabort- > serr- <perr- intx-
latency: 64 (3000ns min, 6000ns max), cache line size: 32 bytes

and then some more about the interrupt...i am guessing the VGAsnoop is what i am looking for?

The section we're looking for from lcpci -vv is

01:00.0 VGA compatible controller: Blahblahblah...

Re: screen goes black with no signal after update?

i cannot see it, but i wonder if its further up on the list as lots of text "fly by" when i hit the command lspci -vv and the first i now see is clock pm- etc.. so i guess it could be further up.. but how do i scroll?

Re: screen goes black with no signal after update?

To control the scrolling, with the spacebar on your keyboard, use

lspci -vv | more

Re: screen goes black with no signal after update?

It's been awhile since I had to install an ati driver but, IIRC, the installation procedure also produces an "uninstall.sh" file in the directory where the ati files that the installer creates were stored.

Re: screen goes black with no signal after update?

on "lsmod"

i see fglrx and next it says 2278776 and then 0

other then that i cannot identify any thing which seem like a ati driver to me?

Re: screen goes black with no signal after update?

ok, i think ive managed to purge ati and fglrx....it took a while, but i think they are gone... i will try to reboot now and see if that works...and then try the rest of the steps found on that link... so far so good.. thank you

ps: it says some of these things will be default in lucid, should i instead do a upgrade? as i am unsure about step 2 and 3...

Re: screen goes black with no signal after update?

now i boot straight into tyty1 so atleast i dont need to use the supergrub cd...will try step 2 and 3..

Re: screen goes black with no signal after update?

but how do i get that "now" old kernel downloaded in tty1 and also with the drivers?

[GreyGeek]

Re: screen goes black with no signal after update?

The link to that "old" driver http://support.amd.com/us/gpudownloa...6&lang=English, which you gave in Reply #13, is the link to the current version of the ATI Catalyst Proprietary Driver. Isn't that the same one you just removed?

Re: screen goes black with no signal after update?

sorry i was responding to the post in which i was given a link to a another forum where the topic was discussed....and in that forum they gave several links which was to several sites that had drivers etc.. but i dont get how you are suppose to downlod these drivers in tty1 mode? right now i think i will try to download another driver and then get into my system and then get all these things done as in tty1 mode i am a bit helpless...
