 gather /dev/tty1 (/dev/console) output to a file |
|
For those who want to get the terminal output from the boot messages into a readable file :
| Code: |
dd if=/dev/vcs1 of=/tmp/TTY1screen bs=1 count=9192
|
creates a long one liner file .
To format it i found best to
| Code: |
echo -e `cat /tmp/TTY1screen | tr ' ' '·' | sed 's/···/\\\\n/g'` | sed '/^$/d' | tr '·' ' ' | sed 's/^[[:blank:]]*//g'
|

Must confess that /dev/vcs1 is not included inside the static /dev/ directory BUT /dev/vcs2 , /dev/vcs3 and /dev/vcs4 .
To create one :
| Code: | | [ ! -e /dev/vcs1 ] && mknod /dev/vcs1 c 7 1 |
I have put these into rc.sysinit because the newish mingetty in racy puppy seems to clear the screen automatically
| Code: | [ ! -e /dev/vcs1 ] && mknod /dev/vcs1 c 7 1 && sleep 1
cat /dev/vcs1 >/tmp/vcs1.txt
echo -e "`cat /tmp/vcs1.txt |sed -e 's,\(.\{80\}\),\1\\n,g'`" >>/tmp/vcs1.txt |
The formation works far better now using {80} for sed .
| Code: | [ 4.384260] ldm_validate_partition_table(): Disk read failed.

The above output is for my adjustments to rc.sysinit . It is primarily done to check for drives at bootup by displaying parts of /proc/partitions before kernel modules got loaded .
One USB flash is not recognized at that time and the second SATA HDD is password protected (ldm_validate_partition_table(): Disk read failed) . .
The 72 for kernel modules can be achieved with
| Code: | echo -n " Loading kernel modules..." >/dev/console
.
.
.
MODULECNT=0
.
.
echo add > ${ONEPATH}/uevent #generates an 'add' uevent.
MODULECNT=$((MODULECNT+1))
echo -en "\r$MODULECNT" >/dev/console
sleep 0.02 |
Cheers

What is a 72 kernel ?
The main Puppy kernels had been 2.6.30.5 and 2.6.33.2 .
The Puppy kernels are not configured with to much framebuffer support .
vga=normal is i think the normal rxvt character resolution of 80x24 .
vga=ask would show a wider range of possibilities like 128x50 or 132x60
IF
supported by the BIOS or The Graphics Chip on Board or on Card .
I had only nvidia graphic cards until now ,
which had been pretty robust working with nouveau.ko andor nvidiafb.ko
if configured correctly to the kernel .
Actually i am running a dell desktop board with intel graphics defined by ddcprobe command as
vbe: VESA 3.0 detected.
oem: Intel(r)Broadwater-G Graphics Chip Accelerated VGA BIOS
vendor: Intel Corporation
product: Intel(r)Broadwater-G Graphics Controller Hardware Version 0.0
and by lspci as
00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])
Subsystem: Dell: Unknown device 01da
And Xorg server version 1.3.0 from Puppy 4 series does not like to work with my kernels ,
only with the Puppy default kernels .
Xorg server 1.7.x from Puppy 5 series is OK with them .
Today i booted with vga=ask
and had chosen a vesa mode of 305 like vga=0x305 at the kernel boot line in Grub mneu .
The decimals of 700+ something i don't use ,
/usr/bin/ycalc transforms 305 HEX to 773 DEC .
The bootscreen had been black until the intel graphic drivers and fbcon had been loaded .
Instead of | Code: | | cat /dev/vcs1 > /tmp/vcs1.txt |
it is also possible to use | Code: | | dd if=/dev/vcs1 of=/tmp/vcs1.txt |
And the 72 seems to refer to the 72 kernel module aliases detected in /sys by /etc/rc.d/rc.sysinit .
That value is different every board and every kernel configuration and every acpi parameter .
I had no board until now with values above 100 module aliases .
Every USB port for example includes some module aliases for ehci_hcd and u/ohci_hcd . So 8 USB ports may include 16 module aliases for two drivers .
