kernel option problem: i lost VESA support unsure what options caused it ?!


i can boot with intel integrated graphics or nvidia 1050

i'm using X11R6-4.8 (vesa driver avoids need of any video driver btw, and is all i want or need)

linux-4.16.12, latest stable

earlier compilations i had X11 running no problem but i had no networking, usb was goofy, had crashes

so i fixed that by removing "8150" support, using r8169, everything was ok: but no VESA after that. i also added more tcp options because even my old firewall could not load (uses iptables) witihout that. i enabled SMTP for icore duo. i removed ISA etc support (no isa slots right?)

X11 walks the pci find a vesa chip: but it never gets ANY screen descriptions (ie, 1024x768 16bpp @ 24Hz or any Hz: not modelines at all)

NO VESA

I tried building kernels with and without acpi apm

XFree86.0.log and it walks PCI but finds only memory regions: not screen configurations reported. it says it found a vesa chip but not acpi (so i built a k with full acpi: same thing)

i then built a kernel with old isa pci acpi apm p&p anything that might be vesa support related (though they shouldn't be unless they say so?)

NADA, no VESA support, zero, same thing

((I don't want to go through frambuffer support or drm or agp hardware support: these are always like pulling teeth or like getting alsa to work. allot of config changes crossing fingers googling 20 solutioins until one works - can take days. i've done that for a few PC and the time spent ends up wasted _later_. i might just go to qeumu and get my chroot i'd like running to work under some premade qemu image i can't get VESA))

I'd really like VESA working. it's supposed to be an immutable standard (assuming the video card has it not all do, but both mine do).

LSPCI just shows both adapters are present in system.

i can't imagine what KERNEL OPTIONS could be blocking X11R6 VESA driver from getting a list of available modes

no vesa modelines detected - and i haven't a clue what kernel options could be blocking it. ????

it's near impossible to go back to orig config (which was broken) and enable one option at a time. (network, acpi, drivers: it'd take an F'ing week to continually compile one option at a time to see what stops making VESA work)

i'm considering running qemu under windows 10 or High Sierra

i'd rather run linux on real PC or inside VM according to what kernel developer's think is the "goal of lk" if they have a preference

if forgot to say it's for an icore PC with both integrated graphics (intel i think) and an mid-range nvidia card ina slot.

VESA (EE) VESA(0): Cannot shmat() low memory

i'm thinking somwhere in pci settings.

but i just figured out the 2.6 kernel i'm using as "stable" marked just "pm" wasn't for pentium pc: it's for a dell lattitude laptop that had tons of laptop IR WIFI USB and integrated graphics support. weirdness! it's running on a PC (2.6 kernel - the 2.4 one i'm still compiling compiling compiling).

the one where fragile low memory "works" and preserves VESA: a rather fat full support dell latitude 2.6 kernel. ??? with maybe fb vesa modules?

it drives me crazy. i cannot pile through a million chip documents to see what might "rob or pervert" PCI /ISA/VESA

that is how many POSSIBLE WAYS there are to compile a kernel if you have no idea which of a million chips might "require" to do something that "perverts or robs" VESA.

(perhaps divided by a few that are unrelated)

... it didn't work

i tried building the 2.4 kernel with the same options as the 2.6 "pm" kernel

(obviously a excluded to picked new options that would seem as to avoid or support VESA in relation to the 2.6 when forced to choose from new options)

does not work

3107!

trying a few more compilies see of agp or fb junk works, then perhaps fall back to 2.6

but i can't fall back to 2.6 that won't keep running on new systems i'd guess. so qemu might be the _only_ way

win10 "spies" continually - continually dumps user process data to microsoft, for games that's ok. but for bringing an app forward for science use: not ok

that leaves me with "suing everyone" or using imac. (my luck is: i have the upgraded version of the same app on my only imac already, and it's an older one)
