Are you using any other monitor while the LCD is being replaced? Is the whole system under service warrantee? <><Randy <><Randall Grimshaw Room 203 Machinery Hall Syracuse University Syracuse, NY 13244 315-443-5779 rgrimsha(a)syr.edu

Can a graphics card kill an LCD display?
by Jack Howarth 31 Jan '06

31 Jan '06

I have a Fedora Core 4 linux box running the ATI fglrx drivers as packaged by livna.org. Today for the second time a Viewsonic VP201S LCD display died on this machine when attached via DVI. The machine is configured to run slightly below 1600x1200 at 60Hz to avoid sparkling in the graphics when glxgears is run. This is done with a modeline of... ModeLine "1592x1194_60.00" 159.6 1592 1696 1872 2152 1194 1195 1198 1236 -hsync +vsync I have used the same modeline on other linux boxes with ATI cards without problems. The first time the display died the failure occured while I was using the machine. The display was fine and then collapsed down into a cloud of green pixels for a second and then went black. Viewsonic sent back a unit with a different serial number after repair (so I believe it was a replacement and not a repair). This unit worked fine for a couple of months until I found it the display dead yet again. In both failures, the Viewsonic showed a green LED when attached to the Radeon 9600 XT suggesting that it was getting a signal. However the monitor remained dark. Also detaching the display from the card did not bring up the digital signal lost alert on the monitor (however the LED does go amber indicating it recognizes loss of signal). Viewsonic will repair this unit again. However i am very concerned that I have had two identical failures on different units. Is it possible for the Radeon card to kill a LCD display? I have been told that cards can short and damage a LCD but that fact that I see a green lit led on the monitor when attached to the 9600's DVI port suggests the signal is getting through but that the circuitry that drives the image display of the card is dead. Is it possible that a card can randomly freak out and overdrive the display circuitry on a DVI connection damaging the display? I thought LCDs were immune to such damage since they don't use flyback transformers.I am really wondering if I should replace this card before I reattach a repaired VP201 again. However the card doesn't seem to damage a Dell multisync at the same resolution (although it did take a couple months for the repaired/replacement VP201S to die). Thanks in advance for any advice on this. Jack

RE: OT: Email signing
by Styma, Robert E (Robert) 31 Jan '06

31 Jan '06

There is a downside to email signatures. My employer requires me to use Microsoft Outlook to read mail through an Exchange server. I have not found a combination of options to make Outlook process the signature correctly. What I see in the preview window is a blank window with one attachements. For people, like Alexander, whose posts are always worth reading, I have to open the attachement and get a window with 2 attachments. One is the signature and the other the text of the post. The text then opens in the text editor. BTW. I have tried to get Evolution talking to the Exchange server, but there are some path paramters which the contracted IT people will not give me since they are not needed for Outlook and other email interfaces are "unsupported". (Pain in the rear end). Bob Styma

gzip -l problem
by Terry Horsnell 31 Jan '06

31 Jan '06

I think 'gzip -l' is having trouble reporting statistics on files whose uncompressed size is > 4Gbytes. Has anyone else seen this problem? Do I contact Gnu about this? Cheers, Terry. alf1_tsh> gzip -l /scr0/boris/*.gz compressed uncompr. ratio uncompressed_name 2556072487 596983808 -328.1% /scr0/boris/Anopheles_gambiae_FASTAruns.tar 1159485670 4174428160 72.2% /scr0/boris/Apis_mellifera_FASTAruns.tar 2510639403 550125568 -356.3% /scr0/boris/Caenorhabditis_elegans_FASTAruns.tar 2128120566 3518132224 39.5% /scr0/boris/Drosophila_ananassae_FASTAruns.tar 2618523155 506277888 -417.2% /scr0/boris/Drosophila_melanogaster_FASTAruns.tar 2138507079 3865974784 44.6% /scr0/boris/Drosophila_mojavensis_FASTAruns.tar 1699621242 1498527744 -13.4% /scr0/boris/Drosophila_pseudoobscura_FASTAruns.tar 1592022108 1111363584 -43.2% /scr0/boris/Drosophila_simulans_FASTAruns.tar 2059666954 3298607104 37.5% /scr0/boris/Drosophila_virilis_FASTAruns.tar 2363369933 76412928 -2992.9% /scr0/boris/Drosophila_yakuba_FASTAruns.tar 20826028597 19196833792 - 8.4% (totals) e.g. if I gunzip /scr0/boris/Drosophila_yakuba_FASTAruns.tar, I get an 8Gbyte uncompressed file. and I suspect all the negative ratios ars for files which would have uncompressed to > 4Gbytes.
