i got sufficient number of framebuffer based graphic viewing and presentation software with the help of the links you have given me and a littlie bit of searching. i will be soon ready with a cd based linux platform for presentation. a lot of thanks to all those who have helped me so generously. the main advantage of this over knoppix like full cd based distros is that it will be lighter hence more faster and less resource hungry yet will retain the main advantage of knoppix. does this lug has any suggestion for me about it?
now the vesa issue. i have a lot of doz tools which let the vesa mode switch between different resolutions and color depth. it requires direct access of hardware by that tool. but this is not possible in linux because the vesa support in kernel has this limitation and the kernel wont let apps to access hardware that way. as result 'fbset' will return ioctl error. what we need is a kernel patch. i have heard about a accelerated vesa device. what is it? i also can not understand the output of # man vesa. it talks about a vesa xf86config entry. i am confused about it. now the monitor flickering issue. modern day pnp monitors automatically synchronizes to the cards refresh rate. but the problem arises possibly due to the fact that they have inbuilt factory settings for vesa mode. 800x600-60 is one of them. when the cards refresh rate matches to these modes the monitor switches to the factory setting. the mismatch takes place due to fact that neither monitor nor the card is perfect and human eye is quite sensitive in this regard. in ranges near 50 hz the fluorescent lamps running on ac power makes the situation worse. i have not found any tool yet which can change the vesa standard refresh rates. does any one know about any such tool? PS. i am quite luck in this regard. i have a sis6326 with 4mb vram and microtek digisync monitor. thouge it flickers a little in generic mode all of the vesa modes are absolutely flickerless and smooth. jaybrata \ / (+) (+) -- To unsubscribe, send mail to [EMAIL PROTECTED] with the body "unsubscribe ilug-cal" and an empty subject line.
