Linux Mint 19 Cinnamon keyboard and mouse don't work after Slackware 14.2 successful install

Hello people. I have a triple boot in my machine. Windows 10, Linux Mint 19(Cinnamon) and Slackware 14.2 LVWM(delicious distro).

Windows are booting and running ok, Slackware are booting and running all things, but Linux Mint... when i boot into Linux Mint the keyboard and mouse don't work and appear a message about Video Acceleration(i search around the web but i don't find anything who solve this issue).

Before Slackware installation, Mint boot with GRUB. Now, all three OS boot with Lilo. I think i need just a proper configuration in lilo.conf for Linux Mint recognize the things(see the grub information of Mint maybe? but i can't access because the keyboard and mouse don't work on Mint).

My lilo.conf:

# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
# Append any additional kernel parameters:
append=" vt.default_utf8=0"
boot = /dev/sda

#compact # faster, but won't work on all systems.

# Boot BMP Image.
# Bitmap in BMP format: 640x480x8
bitmap = /boot/slack.bmp
# Menu colors (foreground, background, shadow, highlighted
# foreground, highlighted background, highlighted shadow):
bmp-colors = 255,0,255,0,255,0
# Location of the option table: location x, location y, number of
# columns, lines per column (max 15), "spill" (this is how many
# entries must be in the first column before the next begins to
# be used. We don't specify it here, as there's just one column.
bmp-table = 60,6,1,16
# Timer location x, timer location y, foreground color,
# background color, shadow color.
bmp-timer = 65,27,0,255

# Standard menu.
# Or, you can comment out the bitmap menu above and
# use a boot message with the standard menu:
#message = /boot/boot_message.txt

# Wait until the timeout to boot (if commented out, boot the
# first entry immediately):
prompt
# Timeout before the first entry boots.
# This is given in tenths of a second, so 600 for every minute:
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
change-rules
reset
# Normal VGA console
#vga = normal
# Ask for video mode at boot (time out to normal in 30s)
#vga = ask

# End LILO global section
# Windows bootable partition config begins
other = /dev/sda1
label = Windows
table = /dev/sda
# Windows bootable partition config ends
# Linux bootable partition config begins

I hope the community can help me with this issue, thank you! LLSW(Long Live to Slackware! I really found my distro of heart but need Linux Mint need to run too)
