I just completed the LFS project on an Acer Aspire 3003WLCi laptop (many people report it is the same [or almost identical] as the aspire 3000)
The system is rather laggy, whenever I type in a few characters (anywhere) it takes a few seconds for them to flush to the screen. In addition, when I type a series of characters (I'm pretty fast at typing), it does not usually flush more than 5 at a time before experiencing some la again. I can continue to type during this time as the characters are apperantly stored into a buffer (ie. they eventually become flushed to the screen)
I did not have this problem when creating LFS using the LFS LiveCD
I do not have any idea why it would possibly have this problem, so I would appreciate any help regarding this issue. I would be more than happy to provide any information I haave available. I also still have access to the LiveCD if I need to make any modifications
This sounds to me like a problem with your kernel config. Perhaps something to do with how the kernel handles interupts? Try recompiling the kernel. Pay particular attention to the Device Drivers ---> ATA/ATAPI/MFM/RLL support ---> menu. You need to enable support for whatever chipset is in your computer. lspci (part of pci-utils) can help.
Well, I did as you said I set 2 or 3 options enabling my SiS chipset... didn't really do anything. Maybe I *still* missed something, but I'm afraid it doesn't work
the actual system is NOT slow- it displays output on the fly at a very fast and fluid rate (no "breaks" or "pauses" like input). The boot up goes fast, and I even wrote a quick C program that printed values from 0 to something like 10000000000 and it smoothly ran through the program.
The only time I have problems is when I input data from the keyboard. And, apperantly, if I type in too many characters before the computer has a chance to process it, then some of them (ex: words, phrases) get lost
My processor is an AMD Mobile Sempron 3000+ (it's a laptop computer), and the chipset is a SiSM760GX chipset with integrated Mirage™2 graphics
Heck... to make it easier, these are the specs from the Acer website:
Microsoft® Windows® XP Professional (which, by the way, I can safely dual-boot too); Mobile AMD Sempron™ Processor 3000+ (128KB L2 cache, 1.80GHz, up to 1600MHz system bus); 512MB (256/256) DDR333 SDRAM; 60GB hard drive; integrated CD-RW/DVD-ROM combo drive; 15.4" WXGA (1280 x 800) TFT display with Acer® CrystalBrite Technology; SiSM760GX chipset with integrated Mirage™2 graphics; 802.11b/g WLAN, 10/100 LAN, V.92 modem
Since the problem only happens when you are entering text from the keyboard, it most be the software that accepts and buffers the keyboard input. I remember discussing that in a C class back in the early 90s. Check in that direction - terminal I/O.
